Access to properties of JSON in Node JS

I'm trying to access the age but I cannot, how can I do that?

var json = '{"carlos":{"data":{"age":"30","phone":"3226458186"}}}';
var obj = JSON.parse(JSON.stringify(json));

This doesn't work for me, obj.carlos is undefined

console.log("Age of Carlos: ", obj.carlos.data.age);

the problem here is the unnecessary call to JSON.parse(JSON.stringify(json)) conver javascript object to JSON like: JSON.parse(json) 

example : 

 var json = '{"carlos":{"data":{"age":"30","phone":"3226458186"}}}';
 var obj = JSON.parse(JSON.stringify(json));
 console.log("Phone of Carlos: ", obj.carlos.data.phone);

No need to JSON.stringify. You just only need to parse your values as they are already a JSON string. Here you go:

var json = '{"carlos":{"data":{"age":"30","phone":"3226458186"}}}';
var obj = JSON.parse(json);

console.log("Age: ", obj.carlos.data.age);

You cannot use JSON.stringify() here, because this method converts a JavaScript object or value to a JSON string and you already got a JSON string. So your code should look like this:

var json = '{"carlos":{"data":{"age":"30","phone":"3226458186"}}}';
var obj = JSON.parse(json);

The problem here is the unnecessary call to JSON.stringify, that method is used to convert JavaScript objects to JSON, but has nothing to do with deserializing them.

The code that you need is just this:

var obj = JSON.parse(json);
