A javascript library of async functions
Discard elements from an array, in place, that pass an async test. The array is only mutated if and when all iterations are completed successfully.
Returns: Promise - The promise is resolved after every callback is resolved or one is rejected. If iterations complete without rejection, then the array is mutated and the Promise is resolved with an array of the discarded elements.
