I realized we keep doing JSON stringify then eventually parsing it back again and again to copy over objects. This does a dump “clone”, it ignores references and functions but is really fast. I wrote a Underscore.js or Lodash mixin just to do this.

  * This is the shortcut for JSON.stringify then parsing it back.
  * Quick access to simple object copying
  * It does not copy functions
  * @author KahWee Teng
  * @return {Object} Lodash mixin object
_.mixin((function () {
  'use strict'
  return {
    copy: function (object) {
      return JSON.parse(JSON.stringify(object))

There’s just so many ways to doing a clone but this is by far the fastest but then again it depends on your needs. Dump clone I call this.
