Function filter

Filters items in an iterable or asynchronous iterable against a predicate and returns items that evaluated to true.

Example

const filterEven = filter((number: number) => number % 2 === 0);

iterableToArray(filterEven([1, 2, 3, 4])); // [2, 4]
iterableToArray(filterEven([1, 3, 5, 7])); // []
