I have an array,

var test = [{
        id: 0,
        test_id: "Password test",
        pass: 1,
        fail: 5,
        time: 0.03,
        pass_fail: 20,
        comments : [
            {comment : "a comment", commentuser : "user" },
        ]
    };
]

within I want to get the value of comment and commentuser in the object comments. I tried as follows,

JSON.stingify(test.comments) // output : "{"comment":"a comment","commentuser":"user"}"

Is there a way to just get the value ? wanted output : "a comment,user"

Cheers

    If it is an array with only one element you can just get it as follows: var comment = test[0].comments[0].comment; var commentuser = test[0].comments[0].commentuser; Commented Nov 25, 2019 at 13:15
  • var output = ${test[0].comments[0].comment},${test[0].comments[0].commentuser} backticks at the start and end. Commented Nov 25, 2019 at 13:21

Join the Object.values of test[0].comments[0] :

var test = [{
  id: 0,
  test_id: "Password test",
  pass: 1,
  fail: 5,
  time: 0.03,
  pass_fail: 20,
  comments: [{
    comment: "a comment",
    commentuser: "user"
  }]
}]

var result = Object.values(test[0].comments[0]).join(',');

console.log(result);

Or deep destructure the object you want and join the Object.values : 

var test = [{
  id: 0,
  test_id: "Password test",
  pass: 1,
  fail: 5,
  time: 0.03,
  pass_fail: 20,
  comments: [{
    comment: "a comment",
    commentuser: "user"
  }]
}]

var [{
  comments: [obj]
}] = test;

var result = Object.values(obj).join(',');

console.log(result);
