What is the correct format in JSON?

Question

Hi, everyone,

I have a question about the JSON. I am writing a JSON file, but I am not sure which of the following formats are correct. Can anyone help me?

{ "class":
    {
        "number": 2,
        "student": 
        {
        "name": "Tom",
        "age": 1
        },
        "student": 
        {
        "name": "May",
        "age": 2
        }
    }
}  

--------------------------

{ class:
    {
        number: 2,
        student: 
        {
        name: "Tom",
        age: 1
        },
        student: 
        {
        name: "May",
        age: 2
        }
    }
}  

Answer 1

JSON requires the quotes. See http://json.org for the specifications.

In particular, the string production is:

string

""
" chars "
