Stop using Array[index], use Array.at() instead
If you want to learn more, check out the MDN reference for it. You can also read the original proposal for it.
- ECMAScript 2022 introduces at() method in Array, String, TypedArray
-
Learning the new `at()` function, at #jslang
Just like every other array method, it’s type coerced. It’s a problem with all built ins, best not fracture this more in JS without a very good reason. https://github.com/tc39/proposal-relative-indexing-method/issues/40

Javascript ES2021 Summary
For a proposal to be finalized, it needs "Two compatible implementations which pass the acceptance tests" (source). This can mean browsers but also includes transpilers like babel. Chrome - which also includes other browsers now like Edge and Opera - will often release stage 3 features publicly before finalized, and Firefox isn't usually far behind, or sometimes even first, as was the case with the currently stage 3 at() method for arrays. Safari is probably the one you have to worry about the most. They tend to be further behind, I think mostly due to their release cadence being longer. Safari, for example, doesn't yet support private methods whereas the other browsers have supported them for some time now. While private methods are stage 4, they are expected to be part of ES2022 which hasn't been published yet - the current being ES2021.

Can I use .length -1 to call a string value?
Soon we’ll get this nicer version (proposal):

How async/await runs inside forEach, and why it probably doesn't do what you expect
Others have mentioned for await, which probably isn't ideal in the case of getting users by id since it'll only do one request at a time, which is less efficient. There's a proposal for Array.fromAsync() that'll essentially do the same thing...
-
Updates from the 92nd TC39 meeting
Array.fromAsync: Array.fromAsync is to for await as Array.from is to for.
-
New ECMAScript 23 array features
The proposal is described here.
-
Getting async data using map arrow method
It's only a stage 2 spec, but Array.fromAsync() would handle exactly what you want. Polyfill exists too.
-
Updates from the 87th meeting of TC39
Array.fromAsync: Like Array.from but it converts an async iterable (or a sync iterable of promises) to a promise that will resolve to an array.
-
Updates from the 85th meeting of TC39
Array.fromAsync Like Array.from but for async iterators.
