    Thank you, I just learned about Pollyfill and your video was on point. I was working on a story at work that needed this overriding, and it worked. I feel so happy now.

    Conclusion: Deprecate IE and move on. If you check right now both the arrow functions page and the promise page, you¿'ll notice they are basically universally accepted.

    Nice tutorials! Good work.
    On a constructive note, there is only one flaw with your videos: The “intro music” is kinda wonky. I know it sounds petty, but just a marketing tip.

    Why can't you just use arr in your polyfill? How does this know to reference your array?

    Thanks a lot... I understand polyfill now... but I dont' understand why the val of this would refer to the arr ?

    Nice explanation but Eventhough I know "this" I didn't understand there why it refer to the that array exactly. It would have been great if u explained it

    • @misoandramen

      The “this” keyword refers to the instance of the object. In this example he was already intending to use arr. However in any case it just refers to the object that you plan to invoke the method on. So if you had an object apples =[“gala”, “Fuji”] you would invoke apples.forEach(lambda function). In the foreach method we look for “this” and it is referring to apples
