+/**
+ * Emits the given constant value on the output Observable every time the source
+ * Observable emits a value.
+ *
+ * <span class="informal">Like {@link map}, but it maps every source value to
+ * the same output value every time.</span>
+ *
+ * ![](mapTo.png)
+ *
+ * Takes a constant `value` as argument, and emits that whenever the source
+ * Observable emits a value. In other words, ignores the actual source value,
+ * and simply uses the emission moment to know when to emit the given `value`.
+ *
+ * ## Example
+ * Map every click to the string 'Hi'
+ * ```ts
+ * import { fromEvent } from 'rxjs';
+ * import { mapTo } from 'rxjs/operators';
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const greetings = clicks.pipe(mapTo('Hi'));
+ * greetings.subscribe(x => console.log(x));
+ * ```
+ *
+ * @see {@link map}
+ *
+ * @param {any} value The value to map each source value to.
+ * @return {Observable} An Observable that emits the given `value` every time
+ * the source Observable emits something.
+ * @method mapTo
+ * @owner Observable
