How can I convert a comma-separated string to an array?

Question

I have a comma-separated string that I want to convert into an array, so I can loop through it.

Is there anything built-in to do this?

For example, I have this

Answer 1

var array = string.split(',');

MDN reference, mostly helpful for the possibly unexpected behavior of the limit parameter. (Hint: "a,b,c".split(",", 2) comes out to ["a", "b"], not ["a", "b,c"].)
