Member of the starry suite—modular functions for iterable objects.

Status

Applies to the whole suite.

Usage

function asyncRace<T = any, U = any>(
  iterable: Iterable<T>, 
  asyncAction: (item: T) => PromiseLike<U>
  )

Returns a promise that resolves with the first, of the return values of asyncAction called upon each element of iterable, which resolved.

Parameters:

• iterable: Iterable<T> - An iterable collection

A handy shortcut for:

Promise.race([].map(async function() { ... }))

But with iterable support. ☺
