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"
