If you have a string containing the textarea's contents, you can call string.split("\n") to split it into an array (using the newline character as a delimiter).

So if you had a variable called textarea which contained the textarea's value, it would look something like this:

var textarea = "..."; // Get this from somewhere
var data = textarea.split("\n");

If you want to provide cross-platform support, you should also handle Windows-style line breaks (\r\n) by replacing them with POSIX line breaks before calling .split("\n"), like so: string.replace(/\r\n/g, "\n").split("\n"). See this answer for further explanation surrounding Windows/POSIX line breaks.
