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