+/**
+ * Returns an Observable that will resubscribe to the source stream when the source stream completes, at most count times.
+ *
+ * <span class="informal">Repeats all values emitted on the source. It's like {@link retry}, but for non error cases.</span>
+ *
+ * ![](repeat.png)
+ *
+ * Similar to {@link retry}, this operator repeats the stream of items emitted by the source for non error cases.
+ * Repeat can be useful for creating observables that are meant to have some repeated pattern or rhythm.
+ *
+ * Note: `repeat(0)` returns an empty observable and `repeat()` will repeat forever
+ *
+ * ## Example
+ * Repeat a message stream
+ * ```ts
+ * import { of } from 'rxjs';
+ * import { repeat, delay } from 'rxjs/operators';
+ *
+ * const source = of('Repeat message');
+ * const example = source.pipe(repeat(3));
+ * example.subscribe(x => console.log(x));
+ *
+ * // Results
+ * // Repeat message
+ * // Repeat message
+ * // Repeat message
+ * ```
+ *
+ * Repeat 3 values, 2 times
+ * ```ts
+ * import { interval } from 'rxjs';
+ * import { repeat, take } from 'rxjs/operators';
+ *
+ * const source = interval(1000);
+ * const example = source.pipe(take(3), repeat(2));
+ * example.subscribe(x => console.log(x));
+ *
+ * // Results every second
+ * // 0
+ * // 1
+ * // 2
+ * // 0
+ * // 1
+ * // 2
+ * ```
+ *
+ * @see {@link repeatWhen}
+ * @see {@link retry}
+ *
+ * @param {number} [count] The number of times the source Observable items are repeated, a count of 0 will yield
+ * an empty Observable.
+ * @return {Observable} An Observable that will resubscribe to the source stream when the source stream completes
+ * , at most count times.
+ * @method repeat
+ * @owner Observable
