- * Maps each source value (an object) to its specified nested property.
- *
- * <span class="informal">Like {@link map}, but meant only for picking one of
- * the nested properties of every emitted object.</span>
- *
- * ![](pluck.png)
- *
- * Given a list of strings describing a path to an object 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 } from 'rxjs';
- * import { pluck } from 'rxjs/operators';
- *
- * const clicks = fromEvent(document, 'click');
- * const tagNames = clicks.pipe(pluck('target', 'tagName'));
- * tagNames.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link map}
- *
- * @param {...string} properties The nested properties to pluck from each source
- * value (an object).
- * @return {Observable} A new Observable of property values from the source values.
- * @method pluck
- * @owner Observable
