Iterating Over Result Of getElementsByClassName Using Array forEach

iterating-with-getelementsbyclassname-and-foreach.js

var els = document.getElementsByClassName("myclass"); // Creates an HTMLObjectList not an array.

Array.prototype.forEach.call(els, function(el) {
    // Do stuff here
    console.log(el.tagName);
});

// Or
[].forEach.call(els, function (el) {...}); // Creates array on the fly.

Thank you!!!

You sir, are an amazing person! Thank you!
