/**

|
* 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.
|
|
* @param {Function} [predicate=_.identity] The function invoked per iteration.
