Hi i have the below json

{id:"12",data:"123556",details:{"name":"alan","age":"12"}}

i used the code below to parse

var chunk={id:"12",data:"123556",details:{"name":"alan","age":"12"}}
var jsonobj = JSON.parse(chunk);
console.log(jsonobj.details);

The output that i received is

{"name":"alan","age":"12"}

I need to get the individual strings from details say i should be able to parse and get the value of "name".I am stuck here any help will be much appreciated

If you already have an object, you don't need to parse it.

var chunk={id:"12",data:"123556",details:{"name":"alan","age":"12"}};
// chunk is already an object!

console.log(chunk.details);
// => {"name":"alan","age":"12"}

console.log(chunk.details.name);
//=> "alan"

You only use JSON.parse() when dealing with an actual json string. For example:

var str = '{"foo": "bar"}';
console.log(str.foo);
//=> undefined

// parse str into an object
var obj = JSON.parse(str);

console.log(obj.foo);
//=> "bar" 

See json.org for more details
