JSOn 语法可以表示三种类型的值

• 简单值: 可以表达式字符串、数值、布尔值和null。不支持 undefined
• 对象: 对象表示的是一组无序的键值对
• 数组: 数组表示一组有序的值的列表,可以通过数组索引来访问其中的值。数组的值可以是简单值、对象、数组

简单值

"Hello, World!"

对象

{
    "name": "Tom",
    "age": 23,
    "scholl": {
        "name": "Merrimack College",
        "location": "North Andover, MA"
    }
}

数组

    {
        "name": "ZhangSan",
        "id": [
            "123486","123456"
        ],
        "age": 23,
        "gender": "male"
    },
    {
        "name": "LiSi",
        "id": [

        ],
