Is there anyway using the stdlib to map from one array to another array, with the work being done concurrently with async?

Is Promise.all() what you're looking for? https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/all

Promise.all() - JavaScript | MDN

The Promise.all() static method takes an iterable of promises as input and returns a single Promise. This returned promise fulfills when all of the input's promises fulfill (including when an empty iterable is passed), with an array of the fulfillment values. It rejects when any of the input's promises rejects, with this first rejection reason.

Of course thanks.

Is there any significance of Promise.all([...]) vs for await (const x of [...])?
