  JSON.stringify() JSON > string
  JSON.parse() string > JSON

var obj = {prop:"lkhjkl", prop1:[11, "kjkj", 45]};
// Object {prop: "lkhjkl", prop1: Array[3]}
var string = JSON.stringify(obj);
// "{"prop":"lkhjkl","prop1":[11,"kjkj",45]}"
var obj1 = JSON.parse(string);
// Object {prop: "lkhjkl", prop1: Array[3]}
