What is React?
React is a JavaScript library used for building user interfaces for web and native applications. It allows developers to construct interfaces from individual, reusable pieces known as components. Developers, whether working alone or in large teams, use React to efficiently create interactive and dynamic user experiences across different platforms. Developers write components as JavaScript functions, using conditional statements for content display and array methods for lists. They combine these components, such as thumbnails or buttons, into complete screens, pages, and applications. React also uses JSX, a JavaScript syntax extension, to place markup close to rendering logic for easier creation and maintenance of components.
