Why use Babel?

Babel is a toolchain that is mainly used to convert ECMAScript 2015+ code into a backwards compatible version of JavaScript in current and older browsers or environments.

Transform Syntax

Use the latest JavaScript syntax like arrow functions, classes, and async/await without worrying about browser support.

Polyfills

Babel can automatically add polyfills for features that are missing in older environments.
