- * 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.
