一、JSON对象中有两个非常好用的方法：

1 JSON.stringify接收一个JS对象转化为json字符串

2 JSON.parse接受json字符串转化为JS对象

const my={
    name:"dylan",
    age:"18"
    }
    let myObj=JSON.stringify(my)
    console.log(myObj)//"{"name":"dylan","age":"18"}"
    let myStr=JSON.parse(myObj)
    console.log(myStr);//{name: "dylan", age: "18"}

注：JSON对象与普通对象的区别是JSON对象键值对都必须用双引号

二、将字符串转换为json对象

JSON.parse('\[\{"t":"a","v":"b,s,g"\},\{"t":"c","v":"d,h,e"\}\]');
