What is app development?

App development is the process of creating software applications for devices such as computers, phones, tablets, and other electronic devices. It involves designing, coding, testing, and debugging the app to ensure that it functions as intended and meets the needs of its users. There are many different programming languages and frameworks that can be used to develop apps, and the specific technologies used will depend on the platform the app is being developed for, as well as the specific requirements of the app itself.

In app development, it is important to carefully plan and design the app before beginning the coding process. This may involve creating wireframes or mockups to visualize the layout and functionality of the app, as well as defining the user flow and determining which features and functionality will be included. Once the app has been designed, the next step is to write the code using a programming language such as Java, Kotlin, Swift, or C#. This code will define the app’s behavior and how it will interact with the device and its operating system.

After the app has been coded, it is important to test it thoroughly to ensure that it is stable and free of bugs. This may involve running automated tests as well as manually testing the app to ensure that it functions as intended. Once the app has been tested and any issues have been addressed, it is ready to be released to the public, either through an app store or other distribution platform.

App development can be a complex and time-consuming process, but it can also be very rewarding for those who are passionate about creating software that is useful and helps people in their daily lives.

Agile development

Agile development is a software development methodology that emphasizes flexibility, collaboration, and rapid iteration. It is a flexible and iterative approach to project management that allows teams to respond to changing requirements or customer needs quickly and efficiently.

In Agile development, the focus is on delivering working software to customers as quickly as possible, rather than following a strict and inflexible plan. Teams using Agile methodologies often work in short, iterative cycles called “sprints,” during which they complete a set of predetermined tasks and then review and refine their work. This allows teams to constantly assess and adjust their priorities and deliver value to their customers more quickly.

Agile development emphasizes collaboration and communication among team members, as well as a focus on customer needs. It is a popular approach to software development because it allows teams to be more flexible and responsive to change, which can be especially important in today’s fast-paced business environment.

API (Application Programming Interface)

An API (Application Programming Interface) is a set of rules and protocols that allows different software systems to communicate with each other. It specifies how software components should interact and provides a way for different systems to access functionality and data provided by other systems. APIs allow developers to build applications that can be easily integrated with other systems and can make it easier to access and use data from a variety of sources.

Beta testing

Beta testing is the process of testing a product or service by a group of users before it is released to the general public. Beta testing is typically the last phase of testing before a product is officially released, and it is intended to identify any remaining issues or bugs that need to be addressed.

Beta testers are often selected from the intended audience for the product and are given access to a pre-release version of the product to use and provide feedback on. This feedback is then used to refine and improve the product before it is released. Beta testing is an important step in the development process because it allows developers to ensure that their product is of high quality and ready for widespread use.

Bug

A bug is an error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. Bugs can be caused by a variety of factors, including coding errors, compatibility issues, and hardware problems.

When a bug is identified, it is typically logged and tracked so that it can be addressed and fixed by a developer. Bugs can range in severity from minor issues that do not significantly impact the functionality of a program, to major issues that can cause the program to crash or malfunction. Testing and debugging are important processes in software development that help identify and fix bugs before a product is released to the public.

Build

In the context of software development, a build refers to the process of compiling and assembling code and resources into a form that can be run on a computer or other device.

During the build process, the source code of a program is transformed into a executable form that can be run by the computer’s operating system. Builds are often created at various stages of the development process, and they can be used for testing, debugging, and ultimately for releasing the software to the public. The process of creating a build typically involves running a series of tasks such as compiling code, linking libraries, and packaging resources.

Continuous integration

Continuous integration is a software development practice in which code changes are automatically built, tested, and validated every time a team member commits their code changes to the shared repository. The goal of continuous integration is to identify and fix errors as quickly as possible, so that the team can maintain a stable and reliable codebase.

Continuous integration helps teams catch problems early on in the development process, before they become more difficult and time-consuming to fix. It can also help teams work more efficiently and effectively by providing a consistent and automated process for integrating code changes.

CORS (Cross-Origin Resource Sharing)

CORS (Cross-Origin Resource Sharing) is a security feature implemented by web browsers that blocks web pages from making requests to a different domain than the one that served the web page. It is designed to prevent malicious websites from making unauthorized requests to other websites on behalf of the user.

CORS can be used to allow web pages to make requests to a different domain by including appropriate HTTP headers in the server’s response. This allows web developers to build applications that can make API calls to servers on different domains, while still maintaining the security of the user’s data.

CSS (Cascading Style Sheets)

CSS (Cascading Style Sheets) is a stylesheet language used for describing the look and formatting of a document written in HTML.

Agile methodology is a set of principles and practices that are used to guide the development of software and other products. It is based on the Agile Manifesto, which outlines a set of values and principles that prioritize flexibility, collaboration, and rapid delivery.

Agile methodologies are designed to be flexible and responsive to change, and they emphasize short development cycles, continuous delivery, and frequent communication and collaboration between team members. Agile methodologies are widely used in software development and other fields, and they are designed to help teams deliver high-quality products quickly and efficiently. Some popular agile methodologies include Scrum, Lean, and Extreme Programming (XP).

Animation

Alpha testing is a type of software testing that is conducted by in-house developers or a small group of testers at the development site. It is typically the first round of testing that is done on a new product, and it is focused on finding and fixing defects and verifying that the product meets the specified requirements.

Alpha testing is typically done after the product has been implemented and before it is released to a larger group of testers or to the general public. It is an important step in the development process, as it allows the development team to identify and fix problems before the product is released. Alpha testing is usually followed by beta testing, which is a more comprehensive testing phase that is typically done by a larger group of testers.

Backend

The backend of an application is the part of the application that is responsible for storing, processing, and retrieving data. It is the behind-the-scenes part of the application that is not visible to the user, and it typically consists of a server, a database, and an application server.

The backend is responsible for handling tasks such as storing and retrieving data from the database, processing requests from the frontend, and integrating with other systems or services. It is an important part of any application, as it provides the necessary infrastructure and functionality to support the frontend and enable the application to perform its intended tasks. The backend is typically developed by backend developers, who use a variety of technologies and languages to build and maintain the backend of an application.

Binary

Binary is a numbering system that is used to represent data and perform calculations using only two digits: 0 and 1. It is the base-2 numbering system, and it is used extensively in computing and digital systems, as it is a simple and efficient way to represent and manipulate data.

In binary, each digit is called a “bit”, and groups of bits are used to represent numbers, characters, and other types of data. Binary is used to store data in computers and other digital devices, and it is also used to transmit data over networks and the internet. Binary is a fundamental concept in computer science and is an important part of how computers work.

Bluetooth

Bluetooth is a wireless technology that is used to exchange data over short distances. It is a popular choice for connecting devices, such as smartphones, tablets, and laptops, and it is widely used in a variety of applications, including mobile phones, wireless speakers, and wireless headphones.

Bluetooth uses radio waves to transmit data, and it is based on a standardized protocol that defines how devices can discover and connect to each other, as well as how data can be transferred between them. Bluetooth is a convenient and popular way to connect devices wirelessly, and it is supported by many devices and operating systems.

Build automation

Build automation is the process of using software tools to automate the process of building, testing, and deploying software and other products. It is a key part of the software development process, and it is designed to help teams build and deliver products more efficiently and reliably.

Build automation tools can handle tasks such as compiling source code, running tests, and generating documentation, and they can be configured to perform these tasks automatically as part of the build process. Build automation is an important part of many agile development methodologies, and it is widely used by developers to streamline the development process and reduce the time and effort required to build and deliver products.

Cache

A cache is a temporary storage area that is used to hold data that is accessed frequently or that is likely to be accessed again in the near future. Caches are used to improve the performance of systems by reducing the need to access slower storage media, such as hard drives and network servers, and by reducing the amount of data that needs to be transmitted over networks.

Caches are commonly used in computers, web browsers, and other types of systems to store data that is accessed frequently or that is used by multiple applications or processes. Caches are typically implemented using fast memory, such as RAM, and they are designed to store data temporarily and to be cleared or updated when the data becomes stale or is no longer needed.

Cloud computing

Cloud computing is a model of computing in which data and services are delivered over the internet, rather than being stored and processed on a local computer or server. It is a flexible and scalable way to access and use computing resources, and it is based on the idea of delivering computing power, storage, and other resources as a service.

Cloud computing allows users to access and use computing resources on demand, and it is often more cost-effective and convenient than maintaining in-house computing infrastructure. Cloud computing is used by a wide range of organizations and individuals to host websites, run applications, store and process data, and perform other computing tasks. Some of the most popular cloud computing services include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

Code review

Code review is the process of reviewing and checking code for errors, bugs, and other issues before it is deployed or released. It is an important step in the software development process, and it is designed to help ensure that code is of high quality, is maintainable, and is aligned with coding standards and best practices.

Code review is typically conducted by developers, who review the code written by their peers and provide feedback and suggestions for improvement. Code review can be done manually, using tools such as diff and patch, or it can be automated using code review tools. Code review is an important part of many agile development methodologies, and it is often used in conjunction with other quality assurance practices, such as testing and debugging.

Compatibility

Compatibility refers to the ability of different systems, devices, or software to work together and exchange information. It is an important consideration in the development and use of technology, as it allows different products and systems to be used together seamlessly and without the need for complex workarounds or integration efforts.

Compatibility can be a challenge in the tech industry, as different products and systems are often developed using different technologies and standards, and there may be compatibility issues or differences in functionality. To address these issues, many companies and organizations have developed compatibility standards and guidelines to ensure that different products and systems can work together effectively.

Cookies

Cookies are small pieces of data that are stored on a user’s device while they are browsing the internet. They are typically used to remember settings, preferences, and login information, and to track user behavior and activity. When a user visits a website, the website can send a cookie to the user’s device, which is then stored in the user’s web browser.

The next time the user visits the same website, their device will send the cookie back to the website, allowing the website to remember the user’s previous activity and settings. Cookies are often used to personalize the user experience and to provide a more seamless and efficient browsing experience.

CSS framework

A CSS framework is a pre-prepared library of CSS styles that can be used to style and layout a website or web application. CSS frameworks provide a set of standardized, reusable styles that can be used as a foundation for building a web interface, and they can help to save time and effort by providing a range of ready-made design elements and layout options.

CSS frameworks are usually designed to be easy to use and customizable, and they often include a range of features such as responsive grid systems, typography styles, buttons, forms, and other common interface elements. Some popular CSS frameworks include Bootstrap, Foundation, and Semantic UI.

Using a CSS framework can help to ensure that a website or web app has a consistent, professional look and feel, and it can also help to speed up development by providing a set of tried-and-tested styles and layout options that can be easily implemented in a project.

Data binding

Data binding is the process of linking data between a source and a target. In the context of app development, data binding refers to the process of binding data from a backend data source to the user interface of an app. This allows the app to display and manipulate data from the data source in a visual and interactive way.

Data binding can be used to bind data from a variety of sources, including databases, servers, and external APIs. It can also be used to bind data from one element of the user interface to another, such as binding the value of a form field to the text of a label.

Data binding can be implemented in a variety of ways, depending on the technology being used to build the app. Some common approaches to data binding include using an ORM (Object-Relational Mapping) framework to map data between the data source and the app, or using a reactive programming library to establish a two-way binding between the data source and the user interface.

Dependency injection

Dependency injection is a software design pattern that involves providing a component with its dependencies rather than having the component create or obtain them itself. This allows for greater flexibility and modularity in the design of an application, as it allows components to be easily swapped out and replaced without affecting the rest of the application.

In the context of app development, dependency injection can be used to manage the dependencies of different components within an app, such as database access, networking, and other services. By using dependency injection, it becomes easier to test and maintain the app, as the dependencies of each component can be easily mocked or stubbed out for testing purposes.

There are several ways to implement dependency injection in an app, including using a dependency injection framework or library, or using a programming language that has built-in support for dependency injection. Some popular dependency injection frameworks and libraries include Dagger, Spring, and Guice.

Deployment pipeline

A deployment pipeline is a series of automated steps that are followed when releasing new code or updates to an application. The purpose of a deployment pipeline is to ensure that code changes can be easily and consistently deployed to different environments, such as development, staging, and production.

A deployment pipeline typically consists of a number of stages, each of which represents a different environment where the code will be deployed. For example, a deployment pipeline might include stages for building and testing the code, deploying the code to a staging environment for further testing and validation, and finally deploying the code to the production environment where it will be available to users.

Using a deployment pipeline can help to improve the efficiency and reliability of the code deployment process, as it allows teams to automate many of the steps involved in releasing new code. It can also help to reduce the risk of errors or issues being introduced when deploying code, as the pipeline can include automated tests and checks to ensure that the code is working as expected.

DevOps

DevOps is a software development philosophy that aims to bring together developers and operations staff in order to improve the efficiency and effectiveness of the software development and deployment process. The goal of DevOps is to enable teams to build, test, and release software faster and more reliably, while also ensuring that the software is more scalable and maintainable.

DevOps practices often involve the use of automation and collaboration tools to enable developers and operations staff to work more closely together, as well as the use of agile and lean principles to improve the speed and quality of software development. Some common DevOps practices include continuous integration and delivery, infrastructure as code, and the use of agile methodologies.

By adopting a DevOps approach, organizations can improve their ability to deliver software updates and features more quickly and with fewer errors, which can help to increase customer satisfaction and competitiveness.

DNS (Domain Name System)

The Domain Name System (DNS) is a distributed database that is used to translate human-readable domain names (such as example.com) into the numerical IP addresses (such as 192.0.2.1) that are used to identify and locate devices on the internet. When a user types a domain name into their web browser, the DNS system is used to look up the corresponding IP address and connect the user to the correct website. DNS is an essential part of the internet infrastructure, as it allows users to access websites and other online resources using easy-to-remember names rather than numerical addresses.

Docker

Docker is a tool that is used to create, deploy, and run applications in lightweight, isolated containers. Containers are a way to package an application and its dependencies together in a single, portable unit, which can be easily deployed and run on any machine that has the Docker runtime installed.

One of the main benefits of using Docker is that it allows developers to create and test applications in a consistent, predictable environment, regardless of the underlying hardware or software configuration of the host machine. This can make it easier to develop and deploy applications, as it reduces the risk of compatibility issues or configuration errors.

Docker also makes it easy to scale applications, as containers can be quickly and easily deployed across multiple host machines. This can make it easier to manage the resources and capacity of an application, and to ensure that the application is available and performant even when the demand for it increases.

Domain

A domain is a name that is used to identify and locate a website or other internet resource on the World Wide Web. A domain consists of two parts: the name of the domain, which is typically a combination of letters and numbers, and the top-level domain (TLD), which is a suffix that identifies the type of organization or purpose of the domain.

For example, in the domain name “example.com”, “example” is the name of the domain, and “.com” is the TLD. Some common TLDs include “.com” (commercial), “.org” (organization), and “.net” (network).

Domains are used to identify and locate resources on the internet, and they are typically registered and managed by domain name registrars, which are organizations that are authorized to sell and manage domain names. When a user types a domain name into their web browser, the browser uses the Domain Name System (DNS) to look up the corresponding IP address and connect the user to the correct website or online resource.

Encryption

Encryption is the process of converting plaintext data into a coded, scrambled form that can only be read or accessed with a secret key or password. The purpose of encryption is to protect data from being accessed or understood by unauthorized parties, and it is often used to secure sensitive information such as passwords, financial transactions, and personal data.

There are many different algorithms and methods that can be used for encryption, and the choice of which one to use depends on the security requirements and the type of data being encrypted. Some common types of encryption include symmetric key encryption, where the same key is used to encrypt and decrypt the data, and public key encryption, where a pair of keys is used, with one key being used to encrypt the data and the other being used to decrypt it.

Encryption is an important aspect of data security, as it helps to protect the confidentiality, integrity, and availability of sensitive data.

Frontend

The frontend of an application or website refers to the user interface and the client-side code that runs in a user’s web browser. The frontend is responsible for rendering the user interface, handling user input and interactions, and communicating with the backend of the application or website.

The frontend of an application or website is typically developed using languages and technologies such as HTML, CSS, and JavaScript, and it is usually designed to be accessed and used by end users through a web browser.

The frontend of an application or website is often the first thing that users interact with, and it plays a crucial role in the user experience. As such, the design and functionality of the frontend is an important consideration in the development of any application or website.

Full-stack

A full-stack developer is a software engineer who is proficient in all layers of an application’s technology stack. This includes the frontend (client-side) and backend (server-side) of an application, as well as the database, server, and networking infrastructure that supports it. Full-stack developers are able to design, develop, and maintain all aspects of an application, and they are often skilled in a range of programming languages, frameworks, and technologies.

Being a full-stack developer can be a highly sought-after skill in the tech industry, as it allows an individual to work on all aspects of an application and to have a broad understanding of how the different parts of an application fit together.

GPS (Global Positioning System)

The Global Positioning System (GPS) is a satellite-based navigation system that is used to determine the precise location, speed, and direction of a device or vehicle. GPS works by using a network of satellites that orbit the earth and transmit signals back to the surface, which can be received and interpreted by GPS receivers on the ground.

The receiver uses the time delay between the transmission and reception of the signals to calculate its distance from the satellites, and by triangulating the distances from multiple satellites, the receiver can determine its exact location. GPS is used in a wide range of applications, including navigation, tracking, and mapping, and it is an essential part of many modern technologies such as smartphones, tablets, and vehicles.

Gradle

Gradle is an open-source build automation tool that is used to automate the process of building, testing, and deploying software. It is designed to be flexible, powerful, and easy to use, and it is used by many developers and organizations to build and manage their software projects.

Gradle uses a domain-specific language (DSL) based on the Groovy programming language to define the build process, and it is capable of building a wide range of software projects, including Java, C++, and Android applications.

One of the main benefits of using Gradle is that it allows developers to create and maintain complex builds in an efficient and maintainable way, and it integrates well with a variety of development tools and environments. It is also highly extensible, and it can be customized and extended with custom plugins and scripts.

GUI (Graphical User Interface)

A graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices through the use of visual elements such as icons, buttons, and menus. A GUI provides a more intuitive and user-friendly way to interact with an electronic device compared to a command-line interface (CLI), which requires users to input commands using text.

GUIs are commonly used in a wide range of electronic devices and software applications, including computers, smartphones, tablets, and web applications. They are designed to make it easier for users to navigate and interact with an application or device, and they often include features such as windows, menus, buttons, and icons to represent different options and functions.

HTTPS (Hypertext Transfer Protocol Secure)

Hypertext Transfer Protocol Secure (HTTPS) is a secure version of the HTTP protocol that is used to transmit data over the internet. HTTPS is designed to provide an encrypted and secure connection between a client and a server, and it is commonly used to protect sensitive information such as login credentials, financial transactions, and personal data.

To use HTTPS, a website or web application must have a valid SSL (Secure Sockets Layer) certificate, which is a digital certificate that is issued by a trusted certificate authority (CA) and is used to establish the authenticity and security of the connection. When a client connects to an HTTPS-enabled website or web application, the server sends its SSL certificate to the client, and the client uses it to verify the identity and security of the connection.

Hybrid app

A hybrid app is a mobile app that is built using a combination of native and web technologies. Hybrid apps are developed using web technologies such as HTML, CSS, and JavaScript, and they are typically wrapped in a native container that allows them to be installed and run on a mobile device just like a native app.

Hybrid apps offer a number of benefits over native apps, including the ability to run on multiple platforms using a single codebase, and the ability to leverage the power of the web and its wide range of libraries and frameworks. However, hybrid apps can also have some performance limitations compared to native apps, as they rely on the device’s webview to run the web code, which can be slower and less reliable than running native code directly.

In-app purchases

In-app purchases are a feature of mobile apps that allow users to purchase additional content or features from within the app itself. In-app purchases can be used to unlock new levels or features of a game, purchase digital goods or services, or subscribe to a premium version of an app.

In-app purchases are typically made using a user’s payment information that is stored in their device or account, and they can be made with a single tap or click. In-app purchases are a common monetization strategy for mobile apps, and they can be a convenient way for users to access additional content or features without having to leave the app.

JWT (JSON Web Token)

JSON Web Token (JWT) is an open standard that is used to securely transmit data between parties as a JSON object. JWTs are often used to authenticate users and authorize access to APIs and other resources, and they are designed to be simple to use and easy to integrate into different systems.

A JWT consists of three parts: a header, a payload, and a signature. The header and payload are both JSON objects that contain information about the JWT, such as the type of token and the claims being made, and the signature is used to verify the authenticity of the JWT.

JWTs are often used in combination with other security measures such as SSL/TLS to provide a secure and robust authentication and authorization solution. They are widely used in modern web and mobile application development, and they are supported by many popular libraries and frameworks.

Load testing

Load testing is a type of performance testing that is used to determine how a system or application performs under a simulated heavy load. Load testing is typically used to evaluate the performance of an application or system under normal and peak usage conditions, and it is designed to identify bottlenecks and potential failure points that may occur when the system is subjected to a high volume of requests or a large number of concurrent users.

Load testing is often conducted using specialized tools and frameworks that can generate simulated traffic or load on the system being tested. This allows developers and testers to monitor the performance of the system and identify any issues or problems that may arise when it is under load.

Load testing is an important aspect of software development and maintenance, as it helps to ensure that an application or system can handle the expected volume of traffic and user activity, and it can help to identify and resolve potential performance issues before they impact users.

Machine learning

Machine learning is a type of artificial intelligence that enables computers to learn and improve their performance on a specific task without being explicitly programmed. Machine learning algorithms use data to learn patterns and relationships, and they can use this knowledge to make predictions or decisions.

There are many different types of machine learning, including supervised learning, unsupervised learning, and reinforcement learning, and they can be applied to a wide range of problems, including image and speech recognition, natural language processing, and predictive modeling.

Machine learning has become an important part of many modern technologies and applications, and it is widely used in areas such as finance, healthcare, and e-commerce to improve decision-making and automate tasks.

MVC (Model-View-Controller)

Model-View-Controller (MVC) is a software design pattern that is used to structure the development of interactive applications. MVC is based on the idea of separating the different aspects of an application into distinct components, which are known as the model, the view, and the controller.

The model represents the data and the business logic of the application, the view represents the user interface, and the controller acts as an intermediary between the model and the view, handling user input and interactions.

MVC is designed to improve the modularity and maintainability of an application, as it allows developers to work on different parts of the application independently, and it can also improve the performance of an application by allowing the model and the view to be optimized separately. MVC is widely used in the development of web, desktop, and mobile applications, and it is supported by many popular frameworks and libraries.

OOP (Object-Oriented Programming)

Object-Oriented Programming (OOP) is a programming paradigm that is based on the concept of “objects”, which are self-contained units of data and logic that represent real-world entities or concepts. OOP is designed to make it easier to develop and maintain complex software systems by providing a structured way to organize and reuse code.

In OOP, objects are created from templates called “classes”, which define the properties and behavior of the objects. Objects can interact with each other and with the outside world by sending and receiving messages, and they can be modified and extended by adding or modifying their properties and methods.

OOP is based on several core principles, including encapsulation, inheritance, polymorphism, and abstraction, and it is supported by many modern programming languages, including Java, C++, and Python.

ORM (Object-Relational Mapping)

Object-Relational Mapping (ORM) is a programming technique used in software development to convert data between incompatible type systems in relational databases and object-oriented programming languages. It provides a way to interact with relational databases using objects, rather than dealing with database-specific SQL queries. ORM automatically performs the database-related operations like Create, Read, Update, Delete (CRUD) and provides an object-oriented interface for querying and manipulating data. This abstraction makes it easier for developers to work with databases as they can write code in their preferred language, rather than learning and writing SQL.

ORMs can also provide advantages like reduced database access time, improved performance, increased scalability, and better security by hiding implementation details and abstracting database-specific APIs. However, it also has some limitations, like difficulties in handling complex SQL queries, or reducing control over the underlying database.

Pairwise testing

Object-Relational Mapping (ORM) is a technique that allows a programmer to work with a database using an object-oriented paradigm. ORM provides a layer of abstraction between the database and the application, allowing the application to work with a high-level object model that is more intuitive and easier to use than a direct connection to the database. ORM tools can be used to automatically generate the necessary SQL statements to perform database operations, and can also map the results of those statements back to objects in the application.

Persistence

Pairwise testing is a testing technique that aims to ensure that all possible combinations of input values are tested. In pairwise testing, a matrix of all possible combinations of input values is created, and a subset of these combinations is selected for testing. This allows a large number of combinations to be tested in a relatively small number of test cases, reducing the time and effort required for testing. Pairwise testing is particularly useful in cases where there are many input variables and it is not practical to test all possible combinations individually.

Pixel density

Pixel density, also known as pixel resolution or pixels per inch (PPI), refers to the number of pixels that can be displayed in a given area of a display screen. It is a measure of the sharpness and clarity of an image or text on a screen. Higher pixel density means that there are more pixels packed into a given area, resulting in a higher quality and more detailed image. The pixel density of a display is often given in PPI, which indicates the number of pixels per inch on the screen. A higher PPI value generally corresponds to a higher-quality display.

Plugin

A plugin is a piece of software that adds a specific feature or service to an existing software application. Plugins are typically designed to be used with a particular application and provide a way to extend the functionality of that application without the need to modify the application itself.

Plugins are often used to add features such as additional tools, support for different file formats, or integration with other applications. Many software applications, such as web browsers and content management systems, support the use of plugins to allow users to customize and extend the functionality of the application.

Polyfill

that provides a means of supporting a feature or technology that may not be available in all environments. Polyfills are commonly used in web development to provide support for newer or experimental features in older or less capable browsers. For example, a polyfill might provide support for a new JavaScript method or CSS property that is not yet supported by all browsers, allowing developers to use the feature in their code and ensuring that it will work across a wider range of environments.

Polyfills can be used to progressively enhance the functionality of a website or application, providing support for newer features where available and falling back to a more basic implementation in environments where the feature is not supported.

Regex (Regular Expression)

A regular expression, also known as a regex or regexp, is a sequence of characters that defines a search pattern. Regular expressions are often used to perform pattern matching with strings, or to search and replace parts of a string. They can be used to check if a string contains a specified pattern, or to extract data from a string for further processing.

Regular expressions are used in many programming languages and tools, including grep, sed, awk, and perl, as well as in text editors and many other applications. Regular expressions are made up of characters and special symbols that define the pattern to be matched.

Server-side rendering

Server-side rendering refers to the process of generating the HTML for a web page on the server, rather than in the client’s web browser. This can be useful in a number of situations, such as when the content of a page needs to be indexed by search engines, or when the page contains data that needs to be protected from being accessed by the client.

In a server-side rendering setup, the server receives a request for a page, generates the HTML for the page, and then sends the completed HTML back to the client’s browser to be displayed. This is in contrast to client-side rendering, where the browser receives and processes raw data and generates the HTML for the page itself.
