What is Babel JS?

Babel is a JavaScript compiler that allows developers to write code using the latest ECMAScript standards and convert it into a version of JavaScript that is compatible with all browsers. It helps in transforming cutting-edge JavaScript code into versions that can run on older browsers.

Why use Babel in React JS?

React JS is a popular JavaScript library for building user interfaces. However, React code is typically written using JSX (a syntax extension for JavaScript) which is not understood by browsers. This is where Babel comes in – it allows developers to write React code in JSX and then compiles it into plain JavaScript that browsers can understand.

Some benefits of using Babel in React JS include:

• Compatibility: Babel ensures that your React code is compatible with all browsers, regardless of their version.
• Future-proofing: You can write code using the latest ECMAScript standards without worrying about browser compatibility issues.
• Improved code readability: JSX makes React code more readable and maintainable, and Babel helps in converting it into plain JavaScript without losing any functionality.

Overall, Babel is an essential tool for React developers to ensure that their code is cross-browser compatible and future-proofed. By using Babel in React JS, developers can write modern, efficient code without worrying about browser compatibility issues.
