/**

|
* This method is like `_.assignIn` except that it accepts `customizer`
|
7
|
* which is invoked to produce the assigned values. If `customizer` returns
|
8
|
* `undefined`, assignment is handled by the method instead. The `customizer`
|
9
|
* is invoked with five arguments: (objValue, srcValue, key, object, source).
|
10
|
*
|
11
|
* **Note:** This method mutates `object`.
