How to clone the same object to three objects using underscore.js

Question

Hi i get my JSON as an object in the below way:

    {
        "id": "001724",
        "select": false,
        "class": "product",
        "Names": [
          "A",
          "B",
          "C"
        ],
        "available": true,
        "description": "selected product",
        }

And i want to sort my JSON using Underscore.js in my javascript file, i'm trying to clone my main object to "names" objects adding an atrribute "name"

[{
A:[
0:{
    "name":"A"
   "id": "001724",
   "select": false,
   "class": "product",
   "available": true,
   "description": "selected product"

}
]
B:[
0:{
    "name":"B"
   "id": "001724",
   "select": false,       
   "class": "product",
   "available": true,
   "description": "selected product"
}
]
C:[
0:{
   "name":"C"
   "id": "001724",
   "select": false,
   "class": "product",
   "available": true,
   "description": "selected product"
}
]
default:[
0:{
    "name":"B"
   "id": "001724",
   "select": false,       
   "class": "product",
   "available": true,
   "description": "selected product"
}
]
}]

and default array contains same as 'B' array

I'm trying to to achieve this using underscore.js

Have you tried anything at all?

I tried cloning, but how can i add an extra attribute "name" for each object. Yes, we need to use _.clone here, but it doesn't gives the exact output i'm looking for

you can easily add it to the new object: newObj.name = "something";

You can clone an Object in plain JavaScript using Object.create:

if(!Object.create){
  Object.create = function(o){
    function F(){}; F.prototype = o;
    return new F;
  }
}
var clone = Object.create(yourObjectHere);
var anotherClone = Object.create(yourObjectHere);

If you don't clone you're really referring to the original Object, even if the variables are different.
