    "boy":true,
    "language":["chinese", "english"],
    "address":{
        "provice":"shanxi",
        "city":"xian"
    }
};

JSON.stringify();

var jsonString = JSON.stringify(data);
console.log(jsonString);
console.log(typeof(jsonString));

//结果:
 {"name":"yfs","age":28,"boy":true,"language":["chinese","english"],"address":{"p
rovice":"shanxi","city":"xian"}}

//类型:string
var a = '{"name":"yfs","age":28,"boy":true,"language":["chinese","english"],"address":{"p
rovice":"shanxi","city":"xian"}}';

JSON.parse();

var jsObject = JSON.parse(jsonString);
console.log(jsObject);
console.log(typeof(jsObject));

//结果:
{ name: 'yfs',
  age: 28,
  boy: true,
  language: [ 'chinese', 'english' ],
  address: { provice: 'shanxi', city: 'xian' } }
