The React documentation should link to this video.

[@day2dayja110]

That google listening to your thoughts and the algo working in the background lol

[@TheSaintsVEVO]

This channel's videos aren't beginner friendly.. It only helps people who are already familiar with this stuff.

nice man i still don’t get it

[@CodeSketched]

Learned more about hooks in this single video than all my attempts to learn about them over the past several years!

[@rafadydkiemmacha7543]

Interesting, because this video doesn't say anything more than the official guide.

[@CodeSketched]

@@rafadydkiemmacha7543 you're right, but the official documentation never felt welcoming enough to read through all the hooks.

[@ImVengeance]

One thing alot of people miss is that on useState in the setter you can actually pass a function to get the prev state value you for say updating a counter which is the correct way. For example setCount(prevCount => prevCount + 1). if you where to call setCount and try modify the value based on the current count value the state would be modified based on the value at that render time. If you call setCount(count + 1) twice it would only infact increase the value by one as both calls would get the prev rendered value and overwrite each other. Hope this helps

[@souvikchakraborty9900]

wow i knew that we should use prevcount but never truly knew what could go wrong if i didn't. Thank you man.

[@wiz7903]

You always manage to put out a video that i just need in that exact moment. Simply amazing. Keep up the good work

[@pathumjayasuriya5902]

Thanks for quick but clear intro on react hooks.

[@Alex-bc3xe]

most clear, concise and simple explanation on hooks.

[@nukemonk]

In addition to the *useImperativeHandle* hook: you can use this if you have both a *forwardRef* and a *useRef* in your component that you want both to be assign to the same element. You can use the *useImperativeHandle* hook to assign the regular *useRef* ref to the *forwardRef* ref. This is because you can't assign two refs to the same element.

[@steelwolf180]

Really easy to understand and helps to point me in the right direction. For a problem, I was stuck on solving a UI component not updating by itself till I click on another component.

[@anth0ni33]
