Question

I have a one-dimensional array of strings in JavaScript that I’d like to turn into a comma-separated list. Is there a simple way in garden-variety JavaScript (or jQuery) to turn that into a comma-separated list? (I know how to iterate through the array and build the string myself by concatenation if that’s the only way.)

Answer 1

The Array.prototype.join() method:

var arr = ['Zero', 'One', 'Two'];  document.write(arr.join(', '));
