 * 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.
