Underscore : _.each(array, iteratee) ES5.1 : array.forEach(iteratee) And all the other elements... Yes, you are right. But... The "array" is not always an Array. document.getElementsByClassName( 'myClass' ) is not an Array but a DOMNodeList. So document.getElementsByClassName( 'myClass' ).forEach(iteratee) will not work. Same for map, reduce... Underscore (or lodash) makes more that just polyfilling es5 methods.

Do something like: NodeList.prototype.__proto__ = Array.prototype;

var myClass = document.getElementsByClassName('myClass') Array.prototype.slice.call(myClass).forEach(iteratee)
