-/**
- * Groups pairs of consecutive emissions together and emits them as an array of
- * two values.
- *
- * <span class="informal">Puts the current value and previous value together as
- * an array, and emits that.</span>
- *
- * ![](pairwise.png)
- *
- * The Nth emission from the source Observable will cause the output Observable
- * to emit an array [(N-1)th, Nth] of the previous and the current value, as a
- * pair. For this reason, `pairwise` emits on the second and subsequent
- * emissions from the source Observable, but not on the first emission, because
- * there is no previous value in that case.
- *
- * ## Example
- * On every click (starting from the second), emit the relative distance to the previous click
- * ```ts
- * import { fromEvent } from 'rxjs';
- * import { pairwise, map } from 'rxjs/operators';
- *
- * const clicks = fromEvent(document, 'click');
- * const pairs = clicks.pipe(pairwise());
- * const distance = pairs.pipe(
- *   map(pair => {
- *     const x0 = pair[0].clientX;
- *     const y0 = pair[0].clientY;
- *     const x1 = pair[1].clientX;
- *     const y1 = pair[1].clientY;
- *     return Math.sqrt(Math.pow(x0 - x1, 2) + Math.pow(y0 - y1, 2));
- *   }),
- * );
- * distance.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link buffer}
- * @see {@link bufferCount}
- *
- * @return {Observable<Array<T>>} An Observable of pairs (as arrays) of
- * consecutive values from the source Observable.
- * @method pairwise
