for-each 
A better forEach.
Example
Like Array.prototype.forEach but works on objects.
var forEach = require("for-each")
forEach({ key: "value" }, function (value, key, object) {
/* code */
})As a bonus, it's also a perfectly function shim/polyfill for arrays too!
var forEach = require("for-each")
forEach([1, 2, 3], function (value, index, array) {
/* code */
})Installation
npm install for-each
