Despite React's popularity it's so hard to find proper intermediate to advanced explanations about the nuances of the library. Seems like most React developers just copy paste and adjust code until they get the desired outcome. It's for this reason that I love Jack for his contribution to the tutorial landscape.

I don’t think I’ve ever commented on a KZread video, but Jack Herrington is one of the best teachers I’ve seen on the channel. Thank you, Jack. Thank you for a fun time learning state in React!

This instructor is really skilled at explaining in just enough detail, good choice!

I learnt more about useState in 20 mins explained here than in a whole term of web development diploma from conventional education. I am so thankful to value-oriented YT channels like this one, are free sources of knowledge and value to everyone at the cost of an internet connection. Thank you for delivering this content about React

Agreed! I no longer want to learn from conventional education! They set a time frame and just throw everything to you and expect you to know and they considered their job done!

This was one of the most comprehensive tutorials I've watched,. I really like how you gave examples of why the state doesn't change when discussing useState.

This is a really great mini course. Loved it! I went and followed Jack's channel as well! Thanks for putting this together.

wow, this is actually super important and it was so hard to actually find something that covers these concepts so well. thank you!

Jack is actually one of few rare guys that covers and teaches you intermediate topics about react/next and typescript on his channel. One thing that I also like for him is that he with all that knowledge, you hear from the voice that he is still on to ground without any ego-trips, he is there to only teach you and transfer a knowledge. Good job Sensei!

This is the most important video about React I have ever seen in over 3 years of using React. Thank you!

easily the best react video and the best teacher. thank you for doing this !

your always great ,right time providing right course for the subscriber .thanks for the educator

Awesome resource man, Thank you for not just explaining how state management works but how the underlying data structure is handled by JS for example by reference and by value.

Jack is maybe the best intermediate content creator. Glad to see him here!

It's Incredible! Got the actual understanding of state management from this. Kudos to Jack!

Highly instructive, thank you. 18 minutes in, I can't wait to watch the rest

I have been learning react since months but this video just hit different! Jack is so amazing! Only after watching this video did I truly understood stage management!

Thank you sir. Your useEffect video was very informative. i learned the why along with the how

This man is the reason I went from junior to medior. You seriously must watch his videos if you're serious about a career with React.

Awesome tutorial. The only thing missing of the useState video is the classic example with 3 consecutive setCount functions that add 1 but the user get 1 again as a result. Then you teach about previous state!

Thank you very much for this course, I think you explain the best among the lecturers.

Thanks for this, it's really worth the time I have put into it.

Jack is a monument and I'm so glad to see him here on FCC ❤

Fantastic tutorial!! Thank you.

Jack is great. Do whatever he tells you to do. You will thank him later.

Great refresher , Yet learnt some new things.

this is really well explained. thank you

Best of the Best, ty Mr.Herrington a lot. You are really awesome

This is really and awesome video. Many thanks for this!

Jack is the best talking about React and Next 🔥🔥

Masterpiece!

best 2:46 of the day! thanks for sharing!

Loved the squirrel raiding the bird feeder in the start of the video 😂

I'm interested to know how to create this with TypeScript. Excellent tutorial. I will spend the next couple of days to build alongside.

Alright... 7 minutes in and I can already tell this is a good video. So many "tutorials" gloss over the nuances of lines of code and this tutorial doesn't. This tutorial also goes a step further by showing code that you would think would work, but actually doesn't and explains why. For me, I need this. I need to know why something is happening, because under-the-hood/behind-the-scenes magic never works for me in the long run.

This man is just amazing !!!

Next make a Advanced React course. it will help me greatly in my job. Thank you for all the awesome content.

I did a hit on like button, when i was at 17:11 ( setLIst( [...list, name ] ) ). Thank you so much master, for this vauable source

I am on 1:13:40 and I was following along and everything was going fine but then the tutor switched to Typescript and starts teaching in it If they wanted to teach in Typescript they should sticked to it since the beginning or they should have notified that things will be taught in TS later in this course as a person who has no knowledge in TS now i have to learn it then i have come back to this course and resume this course it will just waste the time, for those who don't know TS

One of the greate video. 🤩🤩

Great course, Just one correction In useRef section if we do "useState([{id: idRef.current++ , name:"john"} , {id: idRef.current++, name: "Jane"} ])" then upon every re-render idRef value gets updated two times, that maybe because of the development mode which follows "mount unmount and then again mount lifecycle". Note: "On second entry you will get the id 8 instead of 4"

I've been using React for about a year and a half, but I think I got 50% better at React by just watching this course.

You know it's going to be a good React tutorial when the instructor doesn't use CRA

Hello Jack. Thank you for your time and effort to help improve our skills. Question: I have modified your code slightly where I am importing an array of names instead of hard coding it in the components. I am running into a slight problem where I cannot add a coma and space between the names from the array. how can I add this minor detail? Thank you for your time!

Awesome.. Tutorial Jack... purely delighted... Thank you so much!!! Do you mind telling me what is the theme that you used in visual studio code... really liked it and how all keywords are italic... please help me on this

Hey Jack ! Awesome video man. Clear all the fundamentals in one shot. Can you let me know what VS Code extension you are using, that seems to be doing wonders as well.

Nice course

you always surprise me with the super white bg.

would love to see a tutorial about swr in terms of state management, and maybe compare it to react query

High quality intermediate to advanced React contect

Thanks for the great video Jack! Regarding useReducer, the current React 18 docs examples declare the reducer function *outside* the component body. Besides reusability, is there any reason to do it this way as opposed to declaring the reducer *inside* the component?

I like your teaching technic

Good explanations, can anyone provide some advice about project structure/folders when building medium sized app using hooks for local state and context or maybe zustand for global state ? some boilerplate repo would be appreciated too

Hey @jherr, this video is really incredible! Great job! Any idea why Beedrill is the first Pokemon on the useContext results at 1:40:22, but not on the Jotai results at 2:18:51? Is it because you sliced a different amount? I really like the atomic model. I'm gonna have to try Jotai out.

what nice place jack has to work, in the middle of the woods. I'd like have some place like that.

what extensions are you using? how can you run typescript file apart from others (when you open typescript workbook 19:30) - how does the VSCode shows the result in front of the code?

Hello, I love your videos about kivy)) I have a question: I will develop a mobile app and upload it to the Google Play. What do you think, can I use kivy or it is better to use java? Thank you)

1:13:36 Jack, it gives an error as it is, useRef: it runs ok with values like 1, 2, 3... but then it comes obvious that the ++ increments in the useState are fired every time and the count increases by 5, if in strict mode, or by 3, if you comment out 'strict' mode., so what one can do is to assign numbers: id 1 and id 2 for John and Jane, and start the count with 3. (or 2 and pre-increment the id)

@AKSHAY hey by the way, do you know any best react native course.. 😁

whats the extension he used? like when we want to type onClick function, the extension could show up the recomendation tag and symbol for typing the function.

Cca 17:30 Why not using the "prevState" for updating the array?

Jack is awesome, very knowledgeable and insightful! Nevertheless, I got a few questions: 1. Example with Pokemon context used setSearch function inside a hook. Isn't it a good way to move such functions outside of a hook, changing its signature to expect dispatch as a parameter? As a benefit of this approach you'd make setSearch treeshakable, and wouldn't ship dead code in case a consumer doesn't even need it. 2. Regarding the zustand example... Your setAllPokemon function derives new state based on search criteria and a list of pokemons. The question is why do you prefer keep derived state in a store, and call filtering-sorting function two times in a store, instead of inversion the responsibility to filter sort pokemons IF it is needed to the consumer of the store. As far as I understand you could provide a selector for this purpose, aren't you? (i'm not sure since I haven't used zustand and frankly rarely use react). Btw this separation of concerns is what I liked when you showed vatio. 3. This one is more of a wish than of a question) I would really love to see you explaining the example with simple rxjs state management approach. I guess it would be kinda in a family of atomic state management, but light light weight, isn't it? And I also wondering about having a good analysis of pros and cons of those state managers compared to each other)

Merci

Can someone explain to me what Jack does around the 31 minute mark with the {...state, ...action}. I understand the spread operator syntax, I just can't wrap my head around how this works with a more complex state. Like if I had an array of people with first & last name, how would this shortened reducer function know which values to change? I've spent an hour+ trying to work this out.

Does anybody know what Jack is using that gives prompts when he starts typing? For example, for reduce function syntax at 33min.11sec? What VS extension is it?

Wow

What is the name of the extension you use to auto fill specific lines? Thanks!
