Function toAsync

Converts any synchronous iterable into asynchronous one.

It makes possible to use asynchronous-only operators downstream, while also correctly casting all types in the pipeline, avoiding any ambiguity between synchronous and asynchronous iterables.

const i = pipe(
    toAsync(source), // make iterable asynchronous
    delay(500) // now can use asynchronous operators
);
Copy

• Passing it an already asynchronous iterable will just reuse it.
• All indexed types are optimized for performance.

Throws

TypeError: 'Cannot convert to AsyncIterable' when conversion is not possible.
