A better forEach method than the [].forEach.call(NodeList) hack

forEachFunction

// forEach method, could be shipped as part of an Object Literal/Module
var forEach = function (array, callback, scope) {
    for (var i = 0; i < array.length; i++) {
        callback.call(scope, i, array[i]); // passes back stuff we need
    }
};

// Usage:
// optionally change the scope as final parameter too, like ECMA5
var myNodeList = document.querySelectorAll('li');
forEach(myNodeList, function (index, value) {
    console.log(index, value); // passes index + value back!
});
