Speed of [].forEach.call(...?

Question

I'm a big fan of using the forEach method on nodeLists like this:

var nodes = document.querySelectorAll(".foo");

[].forEach.call(nodes, function (item) {
    //do stuff with item
});

I was wondering though, does doing it that way take longer than the regular way? e.g.

for(var i=0;i<nodes.length;i++){
    //do stuff with nodes[i];
}

Answer 1

Here's a nice performance comparison. According to it Array.forEach is slower than a native for loop.

Answer 2

I know it's an old post but using the forEach method can be done by stealing the Array prototype as well.

NodeList.prototype.forEach = Array.prototype.forEach;
