What is json?

 JSON- Javascript object notation.

-- Lightweight data format for storing and exchanging data(as plain text).

--Language independent.

JSON object example-

{

    "id":1,

    "name":"Rafik",

   "age":20

}

Object members are name value pair. Name and value are delimited by colon(:)

N.B: Name are always in double quote("").

Nested JSON object

{

    "id":1,

    "name":"Sadia siddika muna",

    age:24,

    department:{

                      "name":"english",

                        "department code":101

                    }

}

JSON arrays:

{

     "id":101,

     "name":"muna",

     "address":"Barishal",

     "languages":["java","python","javascript"]

}

Let's see a simple JSON array example having 3 objects.

{

        "employees":[

          {"name":"muna","email":"muna@gmail.com","age":24},

          {"name":"sadia","email":"sadia@gmail.com","age":24},

          {"name":"siddika","email":"siddika@gmail.com","age":24},

 ]

}
