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.
11 *
12 * @static
13 * @memberOf _
14 * @since 2.0.0
15 * @category Array
16 * @param {Array} array The array to modify.
17 * @param {Function} [predicate=_.identity] The function invoked per iteration.
18 * @returns {Array} Returns the new array of removed elements.
19 * @example
20 *
21 * var array = [1, 2, 3, 4];
22 * var evens = _.remove(array, function(n) {
23 * return n % 2 == 0;
24 * });
25 *
26 * console.log(array);
27 * // => [1, 3]
28 *
29 * console.log(evens);
30 * // => [2, 4]
