Simplest object iterator (make object spreadable in console :) )

objectIterator.js

1. Any object
var obj = {
  some: 'thing',
  any: 'key',
  '1': 'first'
}

obj[Symbol.iterator] = function* objectIterator() {
    for (k in this) {
        yield this[k];
    }
}

console.log([...obj]); // ["first", "thing", "key"]

2. Nummeric
var obj = {
  '0': 'zero',
  '1': 'first',
  '2': 'second',
  '3': 'third',
  length: 4
};

obj[Symbol.iterator] = function* objectIterator() {
    for (let index = 0; index < (this.length || 0); index++) {
        yield this[index];
    }
}

console.log([...obj]); // ["zero", "first", "second", "third"]
