1、JSON字符串转化JSON对象

let JSONString = '"userName": "半晨", "password": 20211117';
console.log(JSON.parse(JSONString));
// userName: "半晨", password: 20211117

2、JSON对象转化JSON字符串

let JSONObject =  userName: '半晨', password: '20211117' ;
console.log(JSON.stringify(JSONObject));
// "userName":"半晨","password":"20211117"

3、JSON字符串的输出美化

let beautify = [ userName: '半晨', password: '20211117' ];
console.log(JSON.stringify(beautify, undefined, 2));
// [
//   
//     "userName": "半晨",
//     "password": "20211117"
//   
//  ]
