PolyAsyncIterable.filter() method

Return an iteration of the elements of this for which func(element) returns true.

Signature:

filter<U extends T>(func: IndexedTypePredicate<T, U>): PolyAsyncIterable<U>;

Parameters

Parameter	Type	Description
func	IndexedTypePredicate<T, U>	The function to be called on all elements

Returns:

PolyAsyncIterable<U>

A new PolyAsyncIterable with only elements for which func(element) returned true and correctly narrowed to the type asserted by func

Remarks

Because the func argument is a type predicate, the result iteration will have the type asserted by func.
