/**
|
||
|
|
* This method is like `_.merge` except that it accepts `customizer` which
|
||
|
|
* is invoked to produce the merged values of the destination and source
|
||
|
|
* properties. If `customizer` returns `undefined`, merging is handled by the
|
||
|
|
* method instead. The `customizer` is invoked with six arguments:
|
||
|
|
* (objValue, srcValue, key, object, source, stack).
|
||
|
|
*
|
||
|
|
* **Note:** This method mutates `object`.

*
|
