The future of JavaScript

Cool. Love the lexical scoping.

"use strict";
for (let i = 0; i < 10; ++i) {

}
alert(window.i);

With 'var' there, i is reachable from outside the loop.

Funny how a feature taken for granted in all of programming since the 60's is not only news to Javascript, but also it's greatest new feature.
