* Removes all elements from `array` that `predicate` returns truthy for
|
|
* and returns an array of the removed elements. The predicate is bound to
|
|
* `thisArg` and invoked with three arguments: (value, index, array).
|
|
*
|
|
* If a property name is provided for `predicate` the created `_.property`
|
|
* style callback returns the property value of the given element.
|
|
*
|
|
* If a value is also provided for `thisArg` the created `_.matchesProperty`
|
|
* style callback returns `true` for elements that have a matching property
|
|
* value, else `false`.
|
|
*
|
|
* If an object is provided for `predicate` the created `_.matches` style
|
|
* callback returns `true` for elements that have the properties of the given
|
|
* object, else `false`.
|
|
*
|
|
* **Note:** Unlike `_.filter`, this method mutates `array`.

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

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