Isn't that an object,

Var obj = {name: 'hangsan', id: '000000', sex: 'M', age: 30}

Should it be JSON? JSON has two formats: Object Notation and array notation. The author is talking about arrays, which should be the array representation of JSON. The format is as follows:

Var arr = [{name: "zhangsan", id: "00123456", sex: "m", age: 30}]

The array subscript in js can only be a number, so you can use object to implement similar functions.
