Understanding Promise.all in JavaScript

Is Promise.all still relevant in 2025?

In 2025, async JavaScript looks very different. With tools like Promise.any, Promise.allSettled, and Array.fromAsync, many developers wonder if Promise.all is still worth it. The short answer is yes — but only if you know when and why to use it.

  1. good article, concise summary on the basics & tooling for react hook-component testing. thanks! how do you stub HTTP requests? for example, is there a way to intercept the fetch requests going into the first Formula 1 app on mount use effect hook?

  2. It is just for testing simple react hooks function that you can get from anywhere. You haven’t added Testing for async hook component. :disappointed:

  3. Nice Article! Can you please tell if there is any way to override the default value of the useState(0). For example if I initially want to render the counter using the value 1 instead of 0?

  4. This article and the react addition of hooks makes me want to throw up. If you add state to a pure function, *that function is no longer pure*!! If you add effects to the function, *it is not a pure function!!!*

    The reason this is hard to test is *because* the functions are no longer pure once you do this! There’s a huge amount of context that has to exist for that function to work, none of which is a passed in argument! You can’t have your cake and eat it too.

  5. In the example with Testing async Hook functions I am getting the following error
    Timed out in waitForNextUpdate after 1000ms.
