| * ```ts

| *
| * of("from source")

| * .subscribe(x => console.log(x));

| * // results:
| * // "first"
| * // "second"
| * // "from source"
| * ```
| *
| * @param {...T} values - Items you want the modified Observable to emit first.
| * @param {SchedulerLike} [scheduler] - A {@link SchedulerLike} to use for scheduling
| * the emissions of the `next` notifications.
| * @return {Observable} An Observable that emits the items in the specified Iterable and then emits the items
| * emitted by the source Observable.
| * @method startWith
| * @owner Observable
