What is Babel and How It Helps You Write JavaScript

Babel is a toolchain that is mainly used to convert ECMAScript 2015+ code into a backward-compatible version of JavaScript in current and older browsers or environments. Babel's plugins allow you to use the new syntax, right now without waiting for browser support.

The main reasons to use babel JS are −

• Syntax transformation(Latest JS syntax to backward-compatible syntax.)

• Polyfill features that are missing in your target environment (through @babel/polyfill)

• Source code transformations (code modes)
