+ * Maps each source value to its specified nested property.

+ * <span class="informal">Like {@link map}, but meant only for picking one of
+ * the nested properties of every emitted value.</span>
+ *
+ * ![](pluck.png)
+ *
+ * Given a list of strings or numbers describing a path to a property, retrieves
+ * the value of a specified nested property from all values in the source
+ * Observable. If a property can't be resolved, it will return `undefined` for
+ * that value.
+ *
+ * ## Example
+ *
+ * Map every click to the tagName of the clicked target element
+ *
+ * ```ts
+ * import { fromEvent, pluck } from 'rxjs';
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const tagNames = clicks.pipe(pluck('target', 'tagName'));
+ *
+ * tagNames.subscribe(x => console.log(x));
+ * ```
+ *
+ * @see {@link map}
+ *
+ * @param properties The nested properties to pluck from each source
+ * value.
+ * @return A function that returns an Observable of property values from the
+ * source values.
+ * @deprecated Use {@link map} and optional chaining: `pluck('foo', 'bar')` is `map(x => x?.foo?.bar)`. Will be removed in v8.
