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. Is logrocket a content farm? It increasingly pops up when searching for Rust stuff, but it seems to be mostly basic material with links to other texts on the same site.
    The click-bait title of this article is misleading. This is not a deep dive, at best it is a superficial introduction. It also contains errors.

    1. Closures does not “create a reference to the entities in its scope”, this doesn’t compile:
    “`
    fn main() {
    let foo: String = String::from(“hello”);
    let c = |x| {
    let y: &String = x;
    println!(“{}”, y);
    };
    c(foo);
    }
    “`

    2. It’s not true that one “cannot iterate through a set of values (arrays, vectors, maps) in Rust using loops”:
    “`
    fn main() {
    let vec = vec![1, 2, 3];
    for i in 0..3 {
    println!(“{:?}”, vec.get(i));
    }
    }
    “`
