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

| * @param {Array} array The array to modify. | |
