Consts

  • no compilation, no types - thus late errors (runtime), 
  • quirks and bizarre behaviors,
  • function scope vs block scope, 
  • hoisting 

Function scope

function test () {
    if (true) {
        var b = 2;
    }
    var a = 1;
    console.log(a); // 1
    console.log(b); // 2
};

  • object/array deconstruction, 
  • lambda expressions,
  • class syntax,
  • modules

  • adds type annotations,
  • autocomplete
