Parse JSON objects by Javascript

Question

I am new into Javascript and actually I'm facing following problem. I get JSON-object by calling an API. I get more than one object, that is fine. The objects are like this:

{"version": 1.0.1,
 "id": 125,
 "name": "Elmos App Test",
 "creationDate": "2017-05-28",
},
{"version": 1.0.4,
 "id": 25,
 "name": "Elmos App Prod",
 "creationDate": "2017-05-25",
},
{"version": 1.1,
 "id": 14,
 "name": "Elmos App Int",
 "creationDate": "2017-04-23",
}

I hope it is not too difficult to identify the JSON here. MY problem is now to save the three names in one variable.

Response of call should be like --> "Your apps are Elmos App Test Elmos App Prod Elmos App Int"

I actually have following Javascriptcode:

function getJSON(callback){
        request.get(url(), function(error, response, body){
            var d = JSON.parse(body);
            var result = d.name;//query for result
            if (result > null){
                callback(result);}
            else
         {
            callback("ERROR");
         }
    });

As you can see i try to save the name into the var result. Hope someone can help me out there. Thank you.

also need to quote the float numbers so your response should look like: [{"version": "1.0.1", "id": 125, "name": "Elmos App Test", "creationDate": "2017-05-28",},{"version": "1.0.4", "id": 25, "name": "Elmos App Prod", "creationDate": "2017-05-25",},{"version": "1.1", "id": 14, "name": "Elmos App Int", "creationDate": "2017-04-23"}] — Liquidchrome

You can use Array#map() to only get the names and then join() to concatenate them

const array = [{"version": "1.0.1", "id": 125, "name": "Elmos App Test", "creationDate": "2017-05-28", }, {"version": "1.0.4", "id": 25, "name": "Elmos App Prod", "creationDate": "2017-05-25", }, {"version": "1.1", "id": 14, "name": "Elmos App Int", "creationDate": "2017-04-23" }],
  name = array.map(a=>a.name).join(' ');
console.log(name);

But obviously you stored the JSON in the array... how can i store the response in the array?

Don't you already have an array ? What kind of data do you get from request.get(url)?
