Thunk To Async Generator

One or more Async Generators fed by a Thunk

Create an object that exposes:

• .asyncGenerator() to create a new async generator that iterates through input
• .next(input) allowing data to be passed in
• .complete() to declare no more input

If there are multiple async generators, each will get a copy of the data created since their point of inception.

Data will be queued until at least one consuming async generator is available.

Todo

• More explicit end of input early termination
• Better testing from a consuming for await loop
