Wow u explain just blow my mind, i was struggling to understand how react life cycle work underhood,but after watching ur video ,it was just a piece of 🍰.u know how to teach complex topic breaking them into pieces, so that even newbie programmer would easily grasp the concept with ease.thank u for wonderful explain.wait for more complex project with all combination of all concept u taught.

[@yashlearnscode5502]

Exactly the tutorial I was looking for. The official documentation was not really making whole lot of sense to me, as the lifecycle was explained in the context of class based components, but this was really good! Subscribed.

[@AnthonySistilli]

Thanks so much for the kind words Yash!!!

[@davidson7838]

Everyone should give a 5 stars to this series.... :)

[@achdiathadit]

I was amazed by your findings about lifecycle via useEffect when it wasn't even listed in the documentation. Thanks Anthony!

[@greendragon4151]

this guy has clear thoughts, clear language; well done!!!!

[@farrukhzaman3444]

your crystal clear explanation forced me to write a thanks comment on your video thanks alot dude! Liked and subscribed

[@yashkhd1100]

This is probably most clear, to the point example of Component lifecycle. Liked and subscribed. I really liked the way you cover complex cases to in your videos. Unlike many paid courses which just stops with basic examples. Keep it up with more videos..!!

[@shivanigaddagimath6105]

Hi Yash! Yes, these videos do help better than courses sometimes! Are you a student currently? Would you be open for internship/job opportunities?

[@srinidhibseshadri5711]

Hey Anthony!! this video series has taught me so much more than most other courses combined. I love how you give out all necessary information while retaining the viewer's interest in the topic. Thank you so much for such awesome content and looking forward to more such videos.

[@shivanigaddagimath6105]

Hi Srinidhi! Yes, these series do help a programmer to learn more. Are you a student or working? Would you be open for internship/job opportunities?

[@iUmerFarooq]

useEffect() perform three lifecycle method at the same time (componentDidMount, componentDidUpdate, componentDidUnmount). Thank you.

[@user-lu4uo1wj5o]

I've been struggling to under stand this for a while. Your video has helped me out a lot! Cheers!

[@danielstill5625]

This video was awesome! Exactly what I needed to understand how the lifestyle works in a hooks component. Thanks!

[@princeanghelion605]

I have seen dozens of tutorials but I was still unable to understand. thanks to you I understood. you explain very well. thank you

[@oshrizafrani]

Good video. 9:25 The right way (or the safety way) is to provide the empty array all the time, except if you want to run it again so you need to provide the state inside the array.

[@Bosbay6902]

The best explanation so far !!!

[@xiangninglin4108]

The most clear explanation about the lifecycle and its connection with hooks!!! Thanks❤️❤️❤️

[@purleedef]

I’ve watched a lot of different react tutorials on YT and your vids/explanations are hands down the best I’ve been able to find. Great work.

[@davidgarcia-rv3fs]

[@haiderimam8977]

Very good teaching style.

[@biaojin5188]

your explaination is perfect, goooooood job bro.

[@misterprecious69]

Super useful tutorial. This is the first video I've seen that explains why the component lifecycle is important to the useEffect hook and how useEffect pertains to the class methods componentDidMount, componentDidUpdate, and componentWillUnmount! Liked and subscribed! Keep up the good work!

[@baskarhosur15]

Crystal clear explanation, thanks for the video

[@korkortbangla4490]

Thanks for clearing this concept. 😊😊

[@surij8376]

[@nareshsachin7967]

Your video helps to me lot. Your explanation make me clear. Please don't Stop to make a react❤️

[@raoof19]

That's was very useful and simplified! thanks a lot!

[@GlobalGlimpses00]

really the best explanation so far.

[@erkany6753]

Thank you for clear explanation! 👍

[@yangtimothy7351]

honestly, the official documentation should link to this tutorial

[@adamgy]

Congrats! I found this really useful since there aren't so many good lifecycle videos out there about functional components. One practical example I would have added is that useEffect with an empty dependency array is often used to fetch data from an API before mounting a component.

[@AnthonySistilli]

Thanks Adam!! Funnily enough, that's the example I use in the next video :)

[@adamgy]

@@AnthonySistilli Haha! That makes sense :) I wasn't watching the series just this video, but I'll check out the other ones as well. Anyway sorry for the spoiler! :D

[@michelium106]

Thank you for your contribution.

[@josephizang6187]

I have found myself looking forward to your videos. Its just good. Keep up the good work

[@am_0x2a]

Really great video! One thing that I was itching to see is: what if you put a console.log() in the main body of the function component (I.e above your useEffect call)? Since the component itself is a function, new folks can really struggle to understand how often the component itself is called and where it fits into the lifecycle. E.g. is it equivalent to a useEffect with no dep array? If so, demonstrating that would be super helpful.

[@santiagohr3439]

I really like the way you explain it. I'll keep watching your React videos

[@AnthonySistilli]

Thanks for the kind words bro!

Hey Anthony, you really inspire me, I love your videos. +1 for poor React documentation -- seriously, why is it so out of date lol

[@WarloardInPcGamer]

Yeah. React team know this issue and decided to completely rewrite documentation. You can see the discussion in official github page

[@kolyaharutyunyan3035]

Great Job, Thanks!

[@ewomazinoe5642]

This video is great, I love the way you explain and break down things, just curious are you going to do a video around a state management tool like context API or Redux. And which would you advise a beginner to learn first.

[@AnthonySistilli]

I definitely will in the coming weeks! I think they're both similar, so it might be worth doing a tutorial / example in both for a beginner!

[@Oranges4DaWin]

Subscribed! Thanks for the great explanation, excited to see more videos! :)
