Getting start with JSON

JSON is based on two structures:

• It is collection of name / value pair. This is in other languages is realized as record, struct , hash table, keyed list, associative array or object.
• An ordered list of values. This is in other languages is realized vector, list, sequence or an array. 

The object is unordered set of name/value pairs.

The object begin with

{ (left brace)

and ends with

} (right brace).

Each name is followed by : (colon) and the name/value pairs are separated by , (comma).

Array values are specified within square brackets [ ]

Here is an example for you to better understand JSON syntax.

{
    "Customer": [
    {
       "id":"101",
       "firstName": "Yuvi",
       "lastName": "C"       
    },
    {
       "id":"102",
       "firstName": "Nimrit",
       "lastName": "Chahal"  
    }
 ]
}

As you can see, that's pretty much it to get forming your JSON data, in the next part of this tutorial we will explore JSON data types.
