Get specific values out of an array

Question

I'm trying to write a little script, which gets me the name of a tag and it's ID out of Asana. I've an original array structured like this:

"data":[{"id":"27724930904,"gid":"27724930904","name":"Tag1"},
{"id":"26724930954,"gid":"26724930954","name":"Tag2"},
{"id":"26109930621,"gid":"26109930621","name":"Tag3"}]}

The goal is, to get two arrays like this:

var tagName = ["Tag1", "Tag2", "Tag3"];
var tagID = ["27724930904", "26724930954", "26109930621"];

The "gid"-number is not needed. It would be great, if the script would get the original array directly from it's URL (https://app.asana.com/api/1.0/tags).

I'm quite new in javascript and even struggling to get the original array from the URL.

Any hints how this could work? Thanks for your help guys.

Have you made any attempt at all so far to accomplish that yourself? Please post what you've tried. Also, your `tagName` and `tagID`s syntax is invalid. — CertainPerformance, Sep 03 '18 at 21:43

I think you want this:

var asana = { "data": 
  [
    { "id": "27724930904", "gid": "27724930904", "name": "Tag1" }, 
    { "id": "26724930954", "gid": "26724930954", "name": "Tag2" }, 
    { "id": "26109930621", "gid": "26109930621", "name": "Tag3" }
  ]
};

var tagName = asana.data.map(item => item.name);
var tagID = asana.data.map(item => item.id);
