Hey, I just wanted to let you know that I graduated this year. I finally have my Bachelor degree in management developement. And this is (partially) thanks to you ! I followed your Netflix tutorial and it helped me tremendously for one of my last assignments. So you can go to sleep tonight knowing you made someone else's life better. I'm 33 and this bachelor degree is my second one. I decided to study it while working for a job I hated in order to get out of it. It already opened so many opportunities to me and completely changed my professional life and my career perspectives. Thanks a lot, I'll keep following your videos because I learn so much every time.

@@slipstream01 I was close to nowhere with React when I followed this. It's a lot to process though so maybe you should do a few tiny exercises to understand the very basics, then start with this. But whatever you do he explains everything he does so you'll be able to follow. But you might struggle to understand what you do. And if you don't understand, well you won't remember.

And also, it would be lovely if we start using typescript in both our nodejs and react builds, that also will cut down a lot of these kind of errors. i don't know why no matter how much of tutorials i watch out there, i always still wait for you to implement such stacks before i really feel comfortable with them, cos your explanations sink so well in my brains at just a glance

@jeffwang8660 Жыл бұрын

It is amazing. I saw another KZfaqr recommended to use useState individually for each state, but I feel your suggestion of using them as an object is much better. I am interested in useReducer. Could you talk about it as well. Thanks!

for the last one, you could wrap the find one in usememo and pass the dependency as id, to prevent calculating it again and again when you have a lot of states.

I'd love a more in-depth look at the useState -> useReducer example you showed - this hook always confuses me (the docs say it should be obvious if I'm familiar with Redux... however I am not familiar with Redux). Same with useMemo and some of the more obscure hooks actually - but I might just be getting greedy asking for them... fantastic video either way!
