Rename json Object name in node.js

Question

How do I rename Object name from Cars to automobiles? I tried using ObjectRenameKeys but it works on the properties within objects not the object name itself.

Original:

"Cars": [
                {

                    "Part": 1
                },
                {

                    "Part": 2
                },
                {

                    "Part": 3
                }
            ],
Expected: 

"Automobiles": [
                {

                    "Part": 1
                },
                {

                    "Part": 2
                },
                {

                    "Part": 3
                }
            ],

You can't really rename properties....just copy Cars and then delete it:

myObject.Automobiles = myObject.Cars;
delete myObject.Cars;
