A polyfill for Object.prototype.forEach
NOTE: I know it's not really a polyfill because it doesn't exist natively in JavaScript, but it's a useful utility and it's not unheard of that we will see this in a future specification.
$ npm install --save object-foreach-polyfill
var objectForEachPolyfill = require('object-foreach-polyfill');
objectForeachPolyfill(function(v, k) {
return true;
});
