React

React is a popular JavaScript library for building user interfaces. It was developed by Facebook and is widely used for creating interactive and dynamic web applications. React follows a component-based architecture, where the user interface is divided into reusable components that manage their own state and can be composed to build complex UIs.

React uses a virtual representation of the DOM, which allows for efficient rendering and updates to the user interface.

React promotes the development of reusable and modular components, making it easier to maintain and scale applications.

React uses JSX (JavaScript XML), an extension to JavaScript that allows you to write HTML-like code within JavaScript, making it easier to describe the structure of components.

React follows a unidirectional data flow pattern, where data flows in a single direction from parent components to child components, making the application easier to understand and debug.

React can also be used for mobile app development using React Native. It allows you to build native mobile apps using JavaScript and shares a significant portion of the codebase between different platforms.

React has a vibrant ecosystem with a rich set of libraries, tools, and community support. It is widely adopted by developers due to its performance, flexibility, and developer-friendly approach.
