json means javascript object notation

Json is used to transfer data as it is kidn of data format

Json used in api

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
