asyncCollect

Callable

• asyncCollect<T>(xs: AsyncTraversable<T>): Promise<T[]>

---

• Collect the values from an AsyncTraversable and return them as an array.

  Example

  await asyncCollect([1, 2, 3])
  // => [2, 3, 4]
  
  await asyncCollect([Promise.resolve(1), Promise.resolve(2), Promise.resolve(3)])
  // => [2, 3, 4]
  
  await asyncCollect(asyncMap([1, 2, 3], (x) => x + 1))
  // => [2, 3, 4]
  
  const asyncFn = <T>(x: T) => Promise.resolve(x)
  async function* foobar() {
    yield await asyncFn('foo')
    yield await asyncFn('Bar')
  }
  await asyncCollect(asyncMap(foobar(), asyncFn))
  // => ["foo", "bar"]
