Javascript: Put array into a text field

How would you go about putting an array into a textarea, each value on its own line? I thought about converting the array to a string, and the commas into new lines, but what if the value of an array item has a comma?

Try with join 

text = array.join("");
document.write(text); // or what ever you would do with text

use the array's join() method:

["a", "b", "c"].join("\n")

If you have a comma delimited array that contains values with unescaped commas, you have an insurmountable problem. You need to convert the array into a string with some other sort of delimiter, preferably the linebreaks you want them to be in the end.
