5 | * This method is like `_.assign` except that it recursively merges own and
|
---|
6 | * inherited enumerable string keyed properties of source objects into the
|
---|
7 | * destination object. Source properties that resolve to `undefined` are
|
---|
8 | * skipped if a destination value exists. Array and plain object properties
|
---|
9 | * are merged recursively. Other objects and value types are overridden by
|
---|
10 | * assignment. Source objects are applied from left to right. Subsequent
|
---|
11 | * sources overwrite property assignments of previous sources.
|
---|
12 | *
|
---|
13 | * **Note:** This method mutates `object`.
