**React** is a popular JavaScript library for building user interfaces. It was developed by Facebook(Meta) and is often used for building single-page applications and mobile applications.

**There are several reasons why React has become so popular:**

**Reusable components:** React allows developers to create reusable components that can be used throughout an application. This makes it easier to build and maintain complex applications.

**Virtual DOM:** React uses a virtual DOM (Document Object Model) to improve performance by limiting the number of DOM manipulation operations required to update the view.

**One-way data flow:** React follows a unidirectional data flow model, which helps to prevent common issues such as cascading updates and makes it easier to reason about the state of an application.

**Strong community:** React has a strong and active community of developers who contribute to the development of the library and create third-party libraries and tools that can be used with React.
JSX: React uses JSX, which is a syntax extension for JavaScript that allows developers to write HTML-like code in their JavaScript files. This can make it easier to build and understand the structure of a React application.

**Compatibility with other libraries:** React can be used with a variety of other libraries and frameworks, making it a flexible choice for building web and mobile applications.

**Popularity of JavaScript:** React is built with JavaScript, which is a widely-used programming language, making it easier for developers who are familiar with JavaScript to learn and use React.

**Performance:** React's virtual DOM and one-way data flow model help to improve the performance of applications by minimizing the number of DOM manipulation operations required to update the view.

**SEO-friendly:** React applications can be made SEO-friendly by rendering the initial HTML on the server and then handling dynamic updates on the client side.

**Large ecosystem:** There is a large ecosystem of tools, libraries, and resources available for React, which makes it easier for developers to find solutions to common problems and to build and deploy applications.

**Easy to learn:** React has a small API and a straightforward syntax, which makes it relatively easy for developers to learn and use.

**Strong documentation:** React has comprehensive documentation that provides clear and detailed information about how to use the library and its various features.

**Wide adoption:** React is used by many large companies and organizations, which can help to build confidence in its stability and reliability.

**Regular updates:** React is actively maintained and developed by Facebook, and new versions and updates are released regularly, which helps to keep the library up-to-date and in line with modern best practices.

**Versatility:** React can be used to build a wide variety of applications, including web, mobile, and desktop applications, which makes it a versatile choice for developers.

**Overall,** React's combination of above points make it a popular choice for building modern web and mobile applications.
