-/**
- * Applies an accumulator function over the source Observable, and returns each
- * intermediate result, with an optional seed value.
- *
- * <span class="informal">It's like {@link reduce}, but emits the current
- * accumulation whenever the source emits a value.</span>
- *
- * ![](scan.png)
- *
- * Combines together all values emitted on the source, using an accumulator
- * function that knows how to join a new source value into the accumulation from
- * the past. Is similar to {@link reduce}, but emits the intermediate
- * accumulations.
- *
- * Returns an Observable that applies a specified `accumulator` function to each
- * item emitted by the source Observable. If a `seed` value is specified, then
- * that value will be used as the initial value for the accumulator. If no seed
- * value is specified, the first item of the source is used as the seed.
- *
- * ## Example
- * Count the number of click events
- * ```javascript
- * import { fromEvent } from 'rxjs';
- * import { scan, mapTo } from 'rxjs/operators';
- *
- * const clicks = fromEvent(document, 'click');
- * const ones = clicks.pipe(mapTo(1));
- * const seed = 0;
- * const count = ones.pipe(scan((acc, one) => acc + one, seed));
- * count.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link expand}
- * @see {@link mergeScan}
- * @see {@link reduce}
- *
- * @param {function(acc: R, value: T, index: number): R} accumulator
- * The accumulator function called on each source value.
- * @param {T|R} [seed] The initial accumulation value.
- * @return {Observable<R>} An observable of the accumulated values.
- * @method scan
- * @owner Observable
