Babel is a free and open-source JavaScript transcompiler that is mainly used to convert ECMAScript 2015+ (ES6+) code into backwards-compatible JavaScript code that can be run by older JavaScript engines. It allows web developers to take advantage of the newest features of the language. [4]
Transpilation is a source-to-source compilation in which newer versions of JavaScript are used, and a transpiler rewrites the source code so that it is supported by older browsers. Usually, transpilers transpile down to ES3 to maintain compatibility with all versions of browsers.

An ECMAScript engine is a software platform that can run code written in ECMAScript, a programming language more commonly known as JavaScript. More formally, an ECMAScript engine is, at least in part, a "conforming implementation" of the ECMAScript programming language specified by the ECMA-262 international standard.
For example, an object that is checked by a contract can be ensured to make contract checks when its methods are eventually invoked. Racket includes both bytecode and JIT (JIT) compilers. The bytecode compiler produces an internal bytecode format run by the Racket virtual machine, and the JIT compiler translates bytecode to machine code at runtime.

CommonJS's specification of how modules should work is widely used today for server-side JavaScript with Node.js. [1] It is also used for browser-side JavaScript, but that code must be packaged with a transpiler since browsers don't support CommonJS. [1]
