5
 * Removes all elements from `array` that `predicate` returns truthy for
6
 * and returns an array of the removed elements. The predicate is invoked
7
 * with three arguments: (value, index, array).
8
 *
9
 * **Note:** Unlike `_.filter`, this method mutates `array`. Use `_.pull`
10
 * to pull elements from an array by value.

 * @param {Array} array The array to modify.
17
 * @param {Function} [predicate=_.identity] The function invoked per iteration.
