The term transpiling is used because it is mostly a matter of tweaking a
bit the syntax (ES6 has an arrow function syntax not present in ES5) and
inserting polyfills. See for example the future version of jQuery
written with ES6 but transpiled to ES5:
https://code.jquery.com/jquery-git.js
Unlike ARM binary, this is still Javascript, the indentation and the
comments are still here. The variables have the exact same name. Most
people wouldn't have any problem of believing that this is the base
source code of jQuery because it looks like how jQuery would have been
written in ES5 JS (like it is with jQuery 1.x and 2.x).
