React is a library because it focuses on providing a specific set of features for building user interfaces. It is designed to handle the view layer of web applications and provides a way to build reusable UI components.

A library is a collection of prewritten code that can be used to perform specific tasks, while a framework is a more comprehensive solution that provides a set of rules and guidelines for building an application. React is a library because it focuses on the view layer and leaves other concerns, such as routing and state management, to other libraries or frameworks.

React can be easily replaced with another JavaScript packages that provide similar functionality. It is easily plugged into an existing technology stack and follows the UNIX philosophy. So, React is a library.

  • React JS and React Native are both open-source JavaScript libraries developed by Facebook for building user interfaces. The main difference between the two is the platform they target.
  • React JS is used for building web applications using JavaScript and React. Developers can use React JS to create reusable user interface (UI) components and manage the state of their application.
  • React Native, on the other hand, is used for building mobile applications for iOS and Android using JavaScript and React. It allows developers to use the same codebase for building apps for multiple platforms, thus saving time and resources.
  • React JS is used for web development and React Native is used for mobile app development.

React is a JavaScript library for building user interfaces, typically used for building front-end (client-side) web applications. React is not a back-end technology, so is not typically used for building the server-side of an application.

  • Angular is a comprehensive framework that offers a clear perspective on the design of your application. The React library is only concerned with UI components. MVC design requires the use of Flux to be implemented, but it offers greater flexibility in terms of code organization.
  • Angular supports both one-way and two-way data binding, whereas React supports only one-way data binding.
  • Angular is a statically typed language that is a superset of JavaScript. React can write JavaScript XML (JSX), although it isn’t included by default.
  • Angular includes Material design components that make UI configuration a breeze. React includes a Material UI library and dependencies.
  • Angular supports dependency injection, while React does not fully enable dependency injection.
  • Angular is an incremental DOM and React is a virtual DOM.
  • Overall, Angular is a more comprehensive solution for building web applications, while React is a more focused and flexible library for building user interfaces.

Babel is a JavaScript transpiler that allows developers to use next-generation JavaScript, including features such as arrow functions, template literals, and destructuring, even if the current browser or JavaScript runtime does not support them natively. In the context of React, Babel is often used to convert JSX, a syntax extension for JavaScript used in React, into regular JavaScript that can be understood by the browser. This allows developers to use JSX in their React components and still have their code run in older browsers.


React is an open-source JavaScript library mainly used for building single-page applications and web applications with complex user interfaces. React allows developers to build reusable UI components and manage their states efficiently, making it a popular choice for building large-scale web applications.

  • There are 20 React libraries and frameworks:
  • Redux: Redux is a JavaScript state management solution. Although it works with other React-like frameworks, it is most typically used in integration with React.
  • Create React App: Create React App is a command-line utility that doesn’t require any development settings. It encourages the construction of your own standard and guides you through the app development process.
  • Rebass: This group of essential components is intended to assist you in designing a stable user interface with user-defined sizes and limitations.
  • React Admin: React Admin is a tool for building B2B admin apps based on REST/GraphQL APIs that may be tweaked by hand.
  • Ant Design: There is a large and loyal customer base for this extensive component collection.
  • Grommet: Grommet is a component library made for mobile-first, accessible, and responsive web projects.
  • Material UI: Google designed this set of components in order to execute their popular Material design.
  • React Spinner: An entertainment factor that keeps visitors engaged as the page loads, preventing them from feeling compelled to leave, resulting in a better user experience.
  • React Bootstrap: React Bootstrap is a user interface package based on the Bootstrap framework. It replaces Bootstrap’s JavaScript with React in order to provide you more control over each component’s form and function.
  • Next.js: A framework for building React applications that are rendered on the server. It provides a set of features such as automatic code splitting, server-side rendering, and static site generation.
  • Gatsby: A framework for building high-performance, statically generated websites and apps with React. Gatsby uses a powerful plugin system to make it easy to source and process data, and it also provides a set of features for building progressive web apps (PWAs).
  • React routing: React Router is the most popular library for handling routing in React. It provides a set of components and APIs that make it easy to add routing to your app.
  • Semantic UI React
    • Blueprint
    • React DnD
    • Styled Components
    • React Fabric
    • React Virtualized
    • React-Motion
    • React Intl
    • React Desktop
    • Evergreen UI
    • MobX

Developers can integrate React with any backend. It’s a good fit for practically any online app, especially if you’re planning to build a huge, complex one.
Choose React if you want to:

  • Increase development speed (and lower development cost).
  • Enhance user experience, so it’s almost like a native app.
  • Get to market faster.
  • Get on-demand help from the community.
  • Lower maintenance costs.
  • Use future-proof technology.

Features of React Fiber:

  • Improved error handling and recovery from errors.
  • Subtrees are rendered into DOM node containers (portals).
  • Support for additional render return types, including fragments and strings.
  • Return of multiple elements from a render function.

React is a JavaScript library that simplifies the process of creating interactive user interfaces. Create basic views for each state of your application, and React will update and render the appropriate components as your data changes.
