Babel is one of the most popular JavaScript transpilers and becomes the industry standard. It allows us to write ES6 code and convert it back in pre-Es6 JavaScript that browser supports.

For example look the below code snippet.
In ES6 (ECMASCRIPT 2015)

const PI = 3.141593;
PI > 3.0 ;
export{PI};

In ES5 after conversion

"use strict";

Object.defineProperty(exports, "__esModule", {
  value: true
});
var PI = 3.141593;
PI > 3.0;
exports.PI = PI;
