Make all Objects iterable in ES6

object_iterator.js

Object.prototype[Symbol.iterator] = function() {
  let props = Object.getOwnPropertyNames(this);
  return {
    next: () => {
       let name = props.shift();
       let done = (name === undefined);
       let value = (done) ? undefined : [name, this[name]];
       return { value, done };
    }
  }
};
