This dep is still needed until node 20 is dropped.

[MichaelDeBoey]

@ljharb Can you explain why?

aria-query returns normal arrays as of v5 for all *.keys() & *.values(), so we don't need iterator helpers and can just use built-in array functionality?

[ljharb]

aha, you're right. in that case, this PR should be able to go to main instead of breaking, yes?

[MichaelDeBoey]

@ljharb Those array functions didn't exist on Node v4 yet, so we can't merge this PR to main

[ljharb]

True. but on main we could replace the iterator helpers with array method packages?

[MichaelDeBoey]

That would indeed be possible, but that would mean that we need to do 2 PRs: 1 on main to use array method packages + 1 on breaking to remove those packages as well and do what I did in this PR

[ljharb]

True. It'd be nice to have both tho :-) also likely the next time i rebase breaking i'll be removing all the relevant array dep usages you add anyways

[MichaelDeBoey]

@ljharb #1020 is already removing all these array function package usages, so I'd rather keep working on breaking to move forward asap tbh
