-/**
- * 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.
- *
- * ![](last.png)
- *
- * It will emit an error notification if the source completes without notification or one that matches
- * the predicate. It returns the last value or if a predicate is provided last value that matches the
- * predicate. It returns the given default value if no notification is emitted or matches the predicate.
- *
- * ## Examples
- *
- * Last alphabet from the sequence
- *
- * ```ts
- * import { from, last } from 'rxjs';
- *
- * const source = from(['x', 'y', 'z']);
- * const result = source.pipe(last());
- *
- * result.subscribe(value => console.log(`Last alphabet: ${ value }`));
- *
- * // Outputs
- * // Last alphabet: z
- * ```
- *
- * Default value when the value in the predicate is not matched
- *
- * ```ts
- * import { from, last } from 'rxjs';
- *
- * const source = from(['x', 'y', 'z']);
- * const result = source.pipe(last(char => char === 'a', 'not found'));
- *
- * result.subscribe(value => console.log(`'a' is ${ value }.`));
- *
- * // Outputs
- * // 'a' is not found.
- * ```
- *
- * @see {@link skip}
- * @see {@link skipUntil}
- * @see {@link skipLast}
- * @see {@link skipWhile}
- * @see {@link first}
- *
- * @throws {EmptyError} Delivers an `EmptyError` to the Observer's `error`
- * callback if the Observable completes before any `next` notification was sent.
- *
- * @param predicate The condition any source emitted item has to satisfy.
- * @param defaultValue An optional default value to provide if last `predicate`
- * isn't met or no values were emitted.
- * @return A function that returns an Observable that emits only the last item
- * satisfying the given condition from the source, or an error notification
- * with an `EmptyError` object if no such items are emitted.
