Question

I’m trying to create a comma-separated list. I want to make sure that the last line won’t have a comma at the end.

This is what I have so far without any commas just the data:

var labelText = $(this).attr("placeholder");
$('div.errors').append(''+labelText+' Required');

Not sure if I should use the map() function for this or do some sort of if statement?

You can use Array.join()

var colors = ["Orange", "Blue", "Red", "Green"];
var string = colors.join(); // Orange, Blue, Red, Green
