React is a front-end framework that allows you to create interactive web applications. The React framework is built on a declarative paradigm to make development easy and efficient. Its declarative approach ensures predictable code and makes debugging easier. React applications typically consist of several components, each of which is responsible for rendering a small, reusable piece of HTML. The components may be nested in each other and can maintain their own state.

React has a large community that is dedicated to supporting it. It also provides an extensive range of extensions to help you with the architecture of your application. Among them are server-side rendering, Flux, Redux, and React Native, which allows you to build cross-platform mobile apps. The extensive support for the framework makes it easier to test your code. Facebook also offers an extension for Chrome developers that allows them to inspect React components directly.

React is an open-source project, and anyone can download the source code to use it. Its libraries address virtually every UI function. React’s library can grow exponentially with community-curated library add-ons. These add-ons range from single UI features to entire React templates.

React also supports virtualization, which enables a web application to scale efficiently. Its virtualization makes it possible to render web pages quickly and efficiently with a minimum number of updates. This reduces the computing power required to render a page. The result is increased performance.
