Understanding JavaScript Scope in the for-loop with var and let

The other day, I was doing a code review where a click handler was not passing the correct value to a function. When I dug into it, guess what I found 🙄? It is just a three-letter fix, replacing var with let. That's it. However, underneath it was the misunderstanding of the JavaScript Scope on the developer's part.

That's what triggered me to create this video. I hope you enjoy watching it.
