honestly this channel is probably the best out there for deep dives into Typescript and React, love your content good sir
Agree
hey i’ve been following for a while now and this is solid. no gimmicks. pure education, learning and excellent content primarily focused in TS and JS +frameworks. would love to see Rust and wasam content integrated with js. excellent work. can’t wait to see your channel blow up beyond 100k.
Great team advice too, even you know the libraries already, "What is easier to review?" is a helpful perspective.
I was 2 videos and decide to subscribe. This channel got the real stuff compared to so many other KZheadrs pretending to be professional developers.
True, this channel deserves to be much bigger - lots of knowledge and very good production quality.
For my money, when it comes to getting these concepts across in an accessible way that goes beyond the superficial while avoiding being mired down, you are absolutely unbeatable. It's a fine line but you walk it expertly!
I don't understand why youtube didn't recommend your channel to me earlier. This video is not only about mastering React context but also the way you refactor/repurpose the components for the use of context and other state managers. Thanks so much because I learn a lot from it.
Love how you Made the comparison between Context and Zustand. I always use Context and didn’t see why I should consider other state management tools. Thank you Jack
Never really understood what context and Redux do, and you explain it so well with clear examples. Thank you!
adding this facade layer is genious
Amazing content, I have been following the channel for a while now. As a Junior dev I can say that this channel motivates me to dive deeper into concepts and try them out on my own in a series of little projects. Keep up the good work and high quality content, Jack!
Incredibly clear and helpful demo. Please keep doing what you're doing. Your channel is by far the best I've found at showing both "the how" and "the why" of very specific and practical React + TypeScript in a very accessible way.
Insanely good video. Perfect level of detail and nice comparison between the different options. I learned a lot from this.
Amazing video Jack, I really enjoy watching the way you write and talk about code. Your channel is absolutely phenomenal.
Thank you for this episode. In my personal ranking this is the best Context explanation I've ever seen
These series of mastering are amazing, Thank you very much man, I have learned lots of things from you and I owe you a lot :)
It's really neat how you go building the example structure till you get on the topic of the video instead of already showing everything done and and explaining. I really liked that :D
Terrific video, and very topical for my team at the moment as it would happen. Thank you as always ☘
WOW! I mean really WOW... You are such a GREAT teacher. Teaching with examples and passing down all that precious knowledge with such an ease. Brilliant. I'm a fan. First video I watch on your channel and I'm subbed forever. I just started learning React 2 months ago and this helps a looootttttt. Thank you sooooo much man. I'll keep coming back for more knowledge as I need to get a job very soon, hopefully.
This is a really really awesome video. Way Way better than all those tutorial style videos which only is a regurgitation of documentation. This actually deepens my understanding and give me ability to judge new state management tools for myself
I think this video changed my life. Well, my frontend architecture but same thing right now.
Fantastic comprehensive overview! Love your videos Jack, been following you for a long time now.
Watched 2 of your videos. great content, very informative and very well edited. Thanks a lot for the effort
The comparison is really good, especially with the profiler. Didn't know that context will make those many changes to the tree. Thank you Jack for the awesome video!
Exactly what I needed, still getting familiar with React and Next JS. Thanks!
Wow. Fantastic tutorial. Your teaching is very clear. Super helpful. Thanks!
This is a high quality video with great content, something really refreshing on KZhead! Thank you very much 🙏
There is a ton to digest here. Will be watching this many times. Thanks Jack!
Another great video….it’s amazing how many little things I learn mixed in with the major topic stuff. Thank you! Also, you are a great salesman for Copilot…the more I watch you write code the more I want it!
This is really really GREAT content Jack, thank you!
Thank you, Jack, You have the best Front-end channel on YT. Keep it up.
Great content as always. Thank you Jack!
So much great things covered in this video. Also a shout-out for passing the set state as a prop and using the callback to get the state value. I never thought of that before!
Great content and easy to understand. Thank you so much
Thanks! This was really helpful, even though I probably need to rewatch and read the docs a couple of times still
Wowww 👏 this is the most thorough explanation on state management I've come across on yt. Definitely sub to this channel. Thanks!
Thank you so much for this great tutorial!
Great video, I’ve learnt a lot from your youtube channel, keep up the great work. Greeting from Morocco.
Bruh this channel is a blessing
Mastering with the MASTER 🔥Every video is great, sometimes too much 😄, I mean I have seen the video even twice because you reach a high level, but with you Jack, I can improve my skills. Thanks ✌🏻
I am pretty impressed with how easy and clearly he manages to explain these concepts... Zustand sounds pretty interesting, I am definitely gonna try it.
Amazing video Jack, thanks for the effort
Thank you for the wonderful video, Jack! I work in this industry for 5 years and yet I found all of your videos amazing and incredibly informative! All your videos are precious gems :) Only one thing I found a little bit hard to follow is the pace you go through your code in the editor. Personally, for me is a little bit hard to follow with that speed. May be for others is okay :) Thank you once again for the cool stuff you're showing to our fellow programmers :)
Just when wet thought we don't deserve this a high quality educative content, you showed up and said we deserve it.
Best in depth explanation and for free woow you are amazing .. Thank you
easy peasy lemon squeezy, thats the master said. Another very informative contents, so excited to watch your videos 🔥🔥🔥
Thank You! Briliant as always.
Thank you so much for this video. Really useful.
VERY GOOD explanation, thank you!
You really know your stuff. This is where I strive to be in the future
I'm new to your channel, loving your videos great content and thank you for teaching with great easy way 😀
In the dark and dangerous world of React over complexity you are beacon of understanding and hope
Love this channel!!!!!!!!!!! My go-to for React/JS stuff cause it covers more than just the basics which is what is needed in the real world env. Thx for the vids Jack!
PS. these days i'm using Apollo Cache/Reactive variables to pass state around instead of React Context but React context is great too.
An awesome resource for understanding state management in React!
I just start career in React js and found the great video that is helpful for me
This is such a rich content. Thanks for this Jack 👏🏽👏🏽👏🏽
Hey Jack I have been watching video after video of yours. I am still in my deep dive of React and MFE's so would be curious if you had a video on managing State / Context via Module Federation, specifically around JWTs and how to control flow in MFEs for valid / invalid sessions. I'll keep looking through your library but this video along with every video you make is so informative. Thanks for publishing such amazing content!!
Thanks Jack, very helpful!
Thank you very much, sir. Great content.
Even some of the paid content out there is not as impressive as your content sir. Thank you so much.
Awesome video thank you so much!
You did it again. I'm a developer for decades now and to be honest, I'm getting very annoyed by all those wanna be's out there. I'm trying to level up my knowledge about react (although I hate it) and every ninja is telling you to use context for global state. My guts feeling told me that is not a good idea. I don't want to rerender everything to update some fields. I even think that prop drilling is better. I follow your channel for a long time now and I'm glad you gave me the answers I was looking for. In a decent and professional way with proper knowledge and terminology. Thank you!
LOVING THIS MASTR SERIES 🖤
I always asked why people use redux for everything, while they could achieve the same with context or simpler state management libs. This video is proof of it. Unfortunately using context takes a lot of care to avoid re-renders, but zustand demonstrate it can look simple and do the job.
Just remember to make sure you use selectors with your zustand hook. :)
Thanks so much for create and share
Really good content! Thank you.
Great stuff as always
Amazing 🔥🔥🔥 thanks, as always
Thank you so mush Jack!
thanks for the ecommerce example, adding it to the project section in my resume. A full fledged ecommerce app with login logout and add to cart functionality 😎
Really nice video! Thank you 🤯
Finally I got the answer of this famous question, what is difference between redux and context. Your channel was always the best. I guess every body can find their question's answer in your channel. good to have you jack🤩
The University of React State is back in session! Thanks Jack. I will want to get Mr. Kato's book.
Great video! Very educational
Great! Thanks!
Great video, thanks.
Great video, Zustand looks very promising
You just dont stop at a superficial layer. Thanks a ton!!!!
Thank you Jack
Thanks!
I used to use Redux (Redux toolkit to be precise) and it's still used for one of my active projects but in my latest project where I created my own CMS from scratch I used purely React Context for local state management and it was a very good experience. It's not like I dislike Redux toolkit (which is a pretty big upgrade on regular Redux imo when it comes to dev experience), but it was really nice to not have to put in a ton of dev time for the project on just state management.
Amazing!!!
Happy Valentines Day... also great content as always, thank you
Jack, you are so amazing. I would be so happy if you can create full stack web development course. I am sure many people (including me) are willing to pay for your course.
My nextjs mentor, thx man
What's funny to me is that I see this video after seeing the newer "Do you NEED context?" videos :D
Your office environment is amazing.
Let me just say what no one else notices… your video lighting and green screen setup is superb! 🙌 As a video guy I know this takes a bit of a setup/tweaking to get such a clean key without green spill around you.
Thanks. I've been working on it and improving it over time. I think the most recent videos have been pretty solid.
Thanks for the deep but not too deep dive in the various state managers; will help my on my next project! Also thanks for the chapters. :)
Hi Jack, thanks for the great video, I've learned a ton. I have never heard of Zustand before and it seems very interesting for my future projects. Would you use it instead of redux?
Great content sir! Do you have a video comparing Zustand and Redux Toolkit?
Amazing
great video!
Nice!
Thank you for the video! Where I can get same syntax highlighting?
one reason I favour the state managers over the context api is that you can access your state even outside your react components and sometimes thats a requirement. not sure if you can do something like. import contextApi from 'mycontextapi'; contextApi.value ... etc.
You are correct. Making the data in the context available externally would be something you would have to implement. But there is `useSyncExternalStore` that you might want to look into. It's designed specifically to connect React components to external state managers. So if something off the shelf doesn't fit your needs there is that.
amazing content
Brilliant
Hey Jack, great explanation as always! Just curious to know that when you used use-context-selector, why did the wrapper re-render?
Always amazing content that’s prepared so well. Curious, what tools you use to make your videos? Would love to dem to my team in the same format
I use ScreenFlow to capture the screen. If I drew on the screen then I was using ScreenBrush and a commodity Gaomon drawing tablet. And then for post production I use the Adobe Suite. Honestly through, in most cases you could get by the just using ScreeFlow and a decent microphone.
amazing
Very neat
I have kind of learned HTML a thousand times over the years and skipped it because JS and CSS where so cool but HTML is so basic it is thought only to beginners I think you are the perfect person to teach us (i.e. We already know * "Hypertext" refers to links that connect web pages to one another, either within a single website or between websites*) you must do an HTML tutorial for people who knows the basics and give us the advanced tools to master HTML in the context of React and with the minimal CSS or styling possible for it to be interesting but focusing only on HTML (in the context of React probably)… 😅😅😅😅 I would love to get my HTML certification 😉😌😜
I love your channel
