Javascript Add Item in Array to string

Question

I am trying to make a multiline string from taking an array of user ids and matching them to the username and then printing the string.

This is what I have so far and am wondering what the proper way to do this would be:

var names;
for(var i in array) {
    var obj = new NSOA.record.oaUser(i);
    var username = obj.name;
    names = names + username;
}

Ideally names would be a string that looks like:

"Smith, Bob, Doe, Jane, Miller, Larry"

Any help you can give would be very much appreciated!

You can use the native `.join` method to combine items in an array. — Daniel Lizik, Jul 31 '15 at 18:27
It is not clear, please elaborate, what are the inputs and what is the expected result — leo.fcx, Jul 31 '15 at 18:27
Why are there line separators in the string? Doesn't it make more sense to maintain an array of these names if you want to output them on separate lines? — Travis J, Jul 31 '15 at 18:29

If you're printing to HTML insert a <br> after each array element in the string:

var names = '';
for(var i in array) {
    var obj = new NSOA.record.oaUser(i);
    var username = obj.name;
    names = names + username + '<br>';
}

Push all the name in an array then finally Join it by any separator.

For example:

var arr = [];

arr.push('Smith');
arr.push('Bob');
arr.push('Doe');
arr.push('Jane');
arr.push('Miller');
arr.push('Larry');

document.write(arr.join(', '));
