I work professionally with React for more than 5 years and still regularly fall into these traps. Understanding these concepts is essential, and this video explains them perfectly. If RU-vid would allow, I would like this video 10 times!

I wish I had found this tutorial earlier. You have explained all the details of one of the most important hooks in a really intuitive manner ! Great work :)

@ramiov3862 Год назад

I've realy never seen any one who explains React hooks so well and all it's possible uses as well as what mistakes to avoid, This kind of knowledge is really what we are missing as junior developers, And i realy appreciate the effort man Thanks !

@kynshra8960 Год назад

Would you say that only juniors watch these types of videos?

@ionitaa Год назад

All the juniors in my team know by heart the count and setTimeout example because it's a common interview question. But when you ask them to demo global state they gg. One guy just left the interview...

@ionitaa Год назад

@@vapeurdepisse What? At the tech interview, 2 of the codepens we give candidates for junior positions are: 1. The useState and setTimeout question. Most people get it right. 2. A quick demo on how to share state acros a component tree. Most people give up or just give bad solutions to this. You don't have to get all code pens right to get hired...

This is by far the most helpful react video I've ever seen, cleared up a ton of questions I had about strict mode and effect hooks

@marctofan824 Год назад

I have never heard a better explanation. Very clear, simple, many examples. Immediately subscribed to the channel

@arnoczkyzoltan6158 Год назад

Köszönöm szépen, a megfelelő tudást kaptam, pont annyira kifejtve, amennyire szükséges és tisztázódott a fejemben sok misztikum.

@leo-phiponacci Год назад

Very useful, I was searching for these frequently, and you have grouped it together in one video, thanks a lot!

@johnbaquerocelis8148 Год назад

Great explainable video, thank you! Only a sneak peek about Axios. Since v0.22.0 we can use the AbortController passing the signal as an option rather than CancelToken as it is deprecated in new versions.

@yoJuicy Год назад

Very good explanation. useEffect is always intimidating! Keep doing the intermediate level help videos!

@Isaac-eh6uu Год назад

What do you mean by intermediate isn't useEffect one of the basic react hooks?

@feritperliare2890 Год назад

@@Isaac-eh6uu yes but to use react in a way that won’t burn a user’s computer you must use convoluted tricks for the hope that you render only 300 times

@CapeSkill Год назад

@@Isaac-eh6uu I wouldnt call useEffect a basic hook. Its the hardest hook for people to understand.

@justnaika Год назад

@@Isaac-eh6uu I watched at least 5 tutorials about use effect , still cannot wrap my head around it. So, yes , I would call it basic
