toAsync() function

AsyncIterable を返します。toAsyncは Iterable 内の Promise 値を処理したい場合に使用します。

Signature:

declare function toAsync<T>(
  iter: Iterable<T | Promise<T>>,
): AsyncIterableIterator<T>;

Example

let acc = 0;
for await (const item of toAsync([1, 2, 3, 4, 5])) {
  acc += item;
}
// acc: 15

// with pipe
await pipe(
  [Promise.resolve(1), Promise.resolve(2), Promise.resolve(3)],
  toAsync,
  map((a) => a + 10),
  toArray, // [11, 12, 13]
);

Try It
