Fastjson Common methods

First, what exactly isJSON ?

JSON is a string of strings except that the elements are labeled with a particular symbol.

{} Double brackets represent objects

[] brackets represent the array

"" In double quotes is a property or value

: A colon indicates that the latter is a value (the value can be a string, a number, or another array or object)

So {"name": "Michael"} can be understood as an object containing the name Michael

And [{"Name": "Michael"},{"name": "Jerry"}] represents an array containing two objects

Of course, you can also use {"Name": ["Michael", "Jerry"]} to simplify the above, which is an object with a name array

Note: {"ABC"} is not in JSON format, the JSON format is in the form of a key-value pair.
