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.

Why tf is Internet Explorer still considered a browser

Great explanation. How were you able to get that glowing font affect for vscode?

[KoltPenny]

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.

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

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.

Can you please tell me what theme you're using on vscode?

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

[golcuk]

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

[vaibhavmatere]
