| 5 | * This method is like `_.update` except that it accepts `customizer` which is
|
| 6 | * invoked to produce the objects of `path`. If `customizer` returns `undefined`
|
| 7 | * path creation is handled by the method instead. The `customizer` is invoked
|
| 8 | * with three arguments: (nsValue, key, nsObject).
|
| 9 | *
|
| 10 | * **Note:** This method mutates `object`.
