+/**
+ * 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
+ * @owner Observable
