Display object in JavaScript array

Question

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

• Konrud: 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;
• Praveen Jaya Kumar Ramesh: var output = ${test[0].comments[0].comment},${test[0].comments[0].commentuser} backticks at the start and end.

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);
