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 string

var str = "January,February,March,April,May,June,July,August,September,October,November,December";

Now I want to split this by the comma, and then store it in an array.

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"].)
