idk why I kept saying "because of how closures work". there are no closures here, just scoping. "because of how scoping works". cheers!

Frontend interview question is another trouble maker, they asked a lot of code cases (terrible object reassignment patterns and abuse variable scope) that you should never use them in code, and then ask you what happen if you use them, some ignorant devs even are pretentious about knowing those non-sense. It cause many Devs to hard memorize them. In fact, you should never know them, they will pollute your knowledge database.

I've been writing React for a few years now and though I know how state works for the most past, you filled in some gaps for me in this single video. Well said. This was helpful!

this is the explanation that I've wanted for a long time. Most of the tutorials explain how hooks work and how not to use them, but those never explain this much. Thanx.

the audio quality of this video is amazingly done, delight for my speakers!

That was really useful! I'm refactoring code from other people that is really full of states and variables, so this will help me decide what to keep and what to change.

Absolutely fantastic video which is absolutely necessary for anyone looking to get into react to watch. Understanding the concepts here really saves so much debugging time. I know because I suffered debugging these kinds of issues for so long lol😅

Great video to remember the concepts behind React ! I've been so immersed in the framework that i was going with the 'everything needs to be a state' mindset. But when a re-render is not needed it is true that you can use generic JS which i forgot ! I might have to update my linters to allow it from time to time ^_^
