var person = {name :'Saad', age : 26, department : {ID : 15, name : "R&D"} };

var stringFromPerson = JSON.stringify(person);

/* stringFromPerson 结果为 "{"name":"Saad","age":26,"department":{"ID":15,"name":"R&D"}}"   */

var personFromString = JSON.parse(stringFromPerson);

/* personFromString 的值与 person 对象相同  */
