Note: Deno.serveHttp() was done in #22034.

Err I don't understand this suggestion :( don't we have iter() equivalent in deno_std?

No, that's deprecated. Should we add it back in? I was wondering whether we should add it back in...

Probably not. Maybe we shouldn't add a suggestion here - this API relies on Reader interface that is also deprecated. So migrating the underlying Reader dictates which API should be used instead.

The Reader interface in deno_std is no longer deprecated, so this might be fine to add back in.

Also, actually, should it not be ReadableStream instead? Both ReadableStream and Deno.iter() are async iterable.

We can either add iter() back to deno_std or suggest ReadableStream.

Let's suggest ReadableStream 👍

I realise doing this all in runtime/js/90_deno_ns.js will be cleaner.
