ko.observableArray-like helper?

[WorldMaker]

childrenBind is intentionally a simplistic, low level tool. Something like ko's foreach binding can be somewhat approximated with:

const childrenBind = arrayObservable.pipe(
  mergeMap(array => from(Array.entries(array))),
  groupBy(([index]) => index),
  map(([, item]) => <SomeComponent item={item} />),
)

But of course this rough guide will have issues with removals from the end of the array and may need some deeper helper anyway. There's some imperative usefulness to ko.observableArray that might be useful to find a way to rebuild either as a childrenBind helper or a childrenBind eventual replacement.

Does reactivehtml/observable-types work out of the box?
