/**
|

|
|
* This method is like `_.assign` except that it recursively merges own and
|
||
|
|
* inherited enumerable string keyed properties of source objects into the
|
||
|
|
* destination object. Source properties that resolve to `undefined` are
|
||
|
|
* skipped if a destination value exists. Array and plain object properties
|
||
|
|
* are merged recursively. Other objects and value types are overridden by
|
||
|
|
* assignment. Source objects are applied from left to right. Subsequent
|
||
|
|
* sources overwrite property assignments of previous sources.
|
||
|
|
*
|
||
|
|
* **Note:** This method mutates `object`.
