* Returns an Observable that emits only the last item emitted by the source Observable. |
|
* It optionally takes a predicate function as a parameter, in which case, rather than emitting |
|
* the last item from the source Observable, the resulting Observable will emit the last item |
|
* from the source Observable that satisfies the predicate. |

* @throws {EmptyError} Delivers an EmptyError to the Observer's `error` |
|
* callback if the Observable completes before any `next` notification was sent. |
|
* @param {function} predicate - The condition any source emitted item has to satisfy. |
|
* @return {Observable} An Observable that emits only the last item satisfying the given condition |
|
* from the source, or an NoSuchElementException if no such items are emitted. |
|
* @throws - Throws if no items that match the predicate are emitted by the source Observable. |
