jQuery .each() - Identify last item

Question

I want to add a comma between a set of strings using the .each() function except for at the end. How is it possible to get rid of that last comma?

When you say "set of strings", what do you actually have? a "set of strings" could be an array, a string, an object, who knows. — Kevin B, Jun 16 '14 at 18:40

$('#mySelector:not(:last)').each

Of course, after the each you'll have to append the last item for this to be a complete solution. – Kevin B Jun 16 '14 at 18:38

Why would you use each on an ID? – j08691 Jun 16 '14 at 18:38
Cause I don't realize I was using an Id. Despite that, replace with your selector, and the syntaxt :not(:last) would be the right one. – Nico Jun 16 '14 at 18:44

FWIW, modern browsers allow you to do this with CSS, very similar to the jQuery solution:

.item:not(:last-of-type)::after {
    content: ', '
}
