      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.

      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!

    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

    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.

  • @lucasishuman
    @lucasishuman 2 года назад +6

    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.

    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.

    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 :)

    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.

    • @jherr

    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!!

    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!

    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.

      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.

    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 😉😌😜

  • @user-fx9pp2qi3q
    @user-fx9pp2qi3q 7 месяцев назад

    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.

    • @jherr
      @jherr  7 месяцев назад

      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.
