Function each
Given an iterator that yields promises or values, returns a promise that is fulfilled with a null value when the iterator has been consumed or the aggregate promise has been fulfilled or rejected.
$onFulfilled is a function that accepts the fulfilled value, iterator index, and the aggregate promise. The callback can invoke any necessary side effects and choose to resolve or reject the aggregate promise if needed.
$onRejected is a function that accepts the rejection reason, iterator index, and the aggregate promise. The callback can invoke any necessary side effects and choose to resolve or reject the aggregate promise if needed.
