var json = '{"name": "Harry", "age": 18, "country": "United Kingdom"}';
 
// Converting JSON encoded string to JS object
var obj = JSON.parse(json);
 
// Accessing individual value from JS object
alert(obj.name); // Outputs: Harry
alert(obj.age); // Outputs: 18
alert(obj.country); // Outputs: United Kingdom
</script>
