Javascript : add/remove json element in json object

Question

I need to modify my JSON Object by add/remove Json element. Here is my JSON Object,

var candidate = {  
   "name":"lokesh",
   "age":26,
   "skills":[  
      "Java",
      "Node Js",
      "Javascript"
   ]
};

I need to remove the element "skills" and output should be like,

{  
   "name":"lokesh",
   "age":26
}

And I again I need to add the element "skills" as string and the output should be like,

{  
   "name":"lokesh",
   "age":26,
   "skills":"javascript"
}

Please help,

Thanks in advance.

Other ways it can be achieved.

For Adding:

candidate["skills"] = "javascript";

For Deleting:

var skill = "javascript";
delete candidate[skill];

or

delete candidate.skills;
