How Do React Hooks Actually Work? React.js Deep Dive #3

[@sanjeettiwari9000]

You just blew my mind with those useEffect and useState implementations. Great work, man.

[@PhilipFabianek]

Thank you! It also blew my mind when I saw it for the first time.

[@zm690]

This series is exactly what I wanted. Beyond the beginner level and understand behind the sense. 😀

[@jayt2257]

I did this very thing with useState so I reversed engineered it in my mind. I asked the same questions about the order and wondered how the counter could be incremented, and I concluded an array and global counter/index. Great work!

[@wlockuz4467]

I just had a mind explosion moment when you showed the custom useState and useEffect hooks. It makes so much sense now why we can't use hooks anywhere but at the top level!

[@anasmostefaoui3027]

I've been looking on the react internal working in many resources, your content is the one that consolidate and visualize it greatly. great job! thanks a lot for all this hard work.

[@BartekSpitza]

Amazing video. This was exactly what I was looking for, sadly I had to scroll several times as the top videos titled with “how react actually works” were all just shallow reiterations of the react API.. thank you!

[@PhilipFabianek]

Thank you!

Hi Philip, thank you (from Uzbekistan) very much for such great tutorial. appreciate your advanced videos.

[@PhilipFabianek]

Thank you!

[@cyberpsybin]

Excellent tutorial. Only doubt remains is as to why React team decided to go with Arrays and indexes to store hooks. We could use objects and as long out component identifies correctly, hook can be retrieved reliably even if all hooks don't run.

[@PhilipFabianek]

Thank you. I agree that it might've been implemented in a different way but there is probably a reason as to why the React team went with arrays.

[@wlockuz4467]

Really interesting questions, did you find any answers to this?

[@leolin652]

Bro casually created MiniReact😅

[@otis2646]

is it fine that i find it little hard to understand

[@PhilipFabianek]

Especially if this is your first time seeing something like this it is completely fine, try to rewatch the video a few times or maybe sleep on it and then you will definitely understand it better

[@sarcasticdna]

This is some god level stuff please keep posting these kind of videos Int`ernet is already full of shitty beginner tutorials 💗💗

[@Virtualexist]

This is Gold content. Learning react was getting very tasteless and like rote learning for me. This was very helpful to rekindle the interest.

[@Nageswararao93]

Excellent video. I'm really impressed on the video's content quality. Looking forward to more videos like this, thanks a lot

[@PhilipFabianek]

[@bishwajeetpandey1570]

[@SahraClayton]

This has just blew my mind, just when I thought I was just starting to understand react

[@LuisAnducho]

This is very well explained! Thank you! Did you put the code for this lesson somewhere?

[@PhilipFabianek]

I'm planning to use CodePen in the future, but for now I uploaded it here: drive.google.com/file/d/1eTApzbYx_jiAhJBbDTsA4FvkHXDbiQMY/view

Thank you, glad you enjoyed it!

[@trannhathao3978]

In reality, setState function is async. Is there any difference with your example?

[@PhilipFabianek]

Yes there is quite a difference. React uses Fibers under its hood (check out the previous video) and the implementation of useState is quite different in reality. If you want to learn more and perhaps see how useState can be implemented in React Fiber, check out pomb.us/build-your-own-react/
