let in ES6
Raw
let.js
if (a < b){
let c = true;
}
// ES6 introduces block scoping with let, which means that in the example above c is only
// available in the if statement vs the example below
if (a < b){
var c = true;
}
// here c is avaiable outside of the if statement, because var is not block-scoped.
