0React.js is a JavaScript library, a library is a collection of pre-written code that developers can use to simplify the process of building user interfaces.
Reasons:
React is based on a component-based architecture, which means you can break down your UI into small, reusable pieces called components. This makes it easier to manage and maintain complex user interfaces.
React uses a virtual DOM to improve performance. Instead of updating the actual DOM directly, React creates a virtual representation of it in memory and updates only the parts of the actual DOM that have changed. This significantly speeds up the process of updating the user interface.
JSX is a syntax extension for JavaScript recommended by React. It allows you to write HTML-like code directly in your JavaScript files. This makes the code more readable and simplifies the process of creating React elements.
