    Beautiful. I didn't think you could have such a refined control of rendering by using hooks like this.

    so basically useTransition is just debouncing the function to be invoked a little bit later(in milliseconds)?

  • @robertomolinasilvera4863
    @robertomolinasilvera4863 10 місяців тому

    React sends one rerender with currentState and isPending:true to component to tell it will start transition. Then it will rerender component with newState if during this rerender (probably slow) another update is raised, async rerender will be stopped

    Quick Question? Can I use the useTransition to put the loading state for side effects functions
    For e.g. if I have to update the user and I'll wrap the start transition on update function.
    I can use the isPending state to show that is updating or likewise.

    Awesome. Simple and clear explanation.
    But I have a question regarding POSTS page.
    How can we resolve the UI freezing issue for Posts page?
    Or how can we load Posts page content faster?
    Can you help me with this?
    Thanks.

    • @cosdensolutions
      @cosdensolutions  7 місяців тому

      only render a few at a time. So either use virtualization, or paginate them and load them 20 at time

    does the useTransition hook work with react's userReducer just like it would be useState?

  • @VuDuc-lw5xp
    @VuDuc-lw5xp 4 місяці тому

    Hi, I can understand the abstract part that useTransition discards non-urgent action and handle urgent action. But can someone help me explain how startTransition discards post behind the scene with Javascript side? Because in my knowledge, when a synchronous is execute like a Post component in video, we can't discard it with outside code. So how useTransition can do that?

  • @StingSting844
    @StingSting844 Рік тому

    Neat. So what happens to components that render direct from manipulations like chart libraries or canvas libraries? They don't work because react has no way to stop them right?

    • @cosdensolutions
      @cosdensolutions  Рік тому

      depends, if they are driven by state, this will control when that state gets interrupted or not

  • @deliotablang823

    seems like same with the suspense lazy load what are the difference between them?

    • @cosdensolutions
      @cosdensolutions  Рік тому +2

      suspense is for delaying the loading of something and this is for interrupting it and prioritising other renders first

    hello,
    Can you explain this one please -
    while (performance.now() - startTime < 1) {
    console.log("entered while...", performance.now());
    // Do nothing for 1 ms per item to emulate extremely slow code
    }
    performance.now() - startTime < 1 should always be greater than 1 isn't it? I don't know why is it going inside the while loop and what does 1ms delay is derived. Would be great if you can please explain.

    • @cosdensolutions
      @cosdensolutions  Рік тому

      this code just forces the component to wait 1ms before continuing the render. It comes from the React docs in their examples! It just simulates slowness so that you can actually see the effects of what you are doing

  • @veerasamysevagen9533

    Hello, Loved your explanation but it does not seem to work with this piece of code.
    const buttonClick = (type: string) => {
    startTransition(() => {
    if(type === "fast") {
    setCounter(25);
    } else {
    setCounter(() => {
    let sum = 0;
    for(let i =0; i

    • @cosdensolutions
      @cosdensolutions  11 місяців тому

      because startTransition works by interrupting renders that take too long after being set, not the actual setting of a new value. In your case, you're just taking a while to set the new value to trigger a re-render, but the actual re-render is super fast as it will just update the counter with one value
