Make fn return a promise?

[t0mclaudio]

I was just wondering if there is a benefit to making the chunkify function return a Promise? I am thinking of a use case where we pass a large iterable data? I'm sorry if this question is a silly one. 😄

It would create more overhead than benefit for most cases. If you really do have a huge data set, you should instead run it in a worker_thread. However, since it's an iterable, you could use it with a for-awaits loop: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for-await...of#iterating_over_sync_iterables_and_generators It will still block the main thread, but at least it will give up the main thread for each iteration.
