Lets look into a json data




        {

            "area": "Newyork",

            "areacode": 350,

            "population": 100000       

        }

Its easy to use

Firstly you have to assign name,then its value

In below example,we use this json data


<!DOCTYPE html>

<html>

<head>

<title>json data use</title>

</head>

<body>



<script>

var jsondata = {

  "area": "Newyork",

  "areacode": 350,

  "population": 100000       

}

document.write(jsondata.areacode);

</script>



</body>

</html>

outptut:

350

so,here we assign json data into a variable,jsondata and by jsondata.areacode we are showing the value of areacode inside jsondata variable
