Question

Sorry for this extreme beginner question. I have a string variable originaltext containing some multiline text. I can convert it into an array of lines like so:

lines = originaltext.split("\n");

But I need help sorting this array. This DOES NOT work:

lines.sort;

The array remains unsorted.

---

And an associated question. Assuming I can sort my array somehow, how do I then convert it back to a single variable with no separators?

Your only issue is a small one – sort is actually a method, so you need to call lines.sort(). In order to join the elements together, you can use the join() method:

var originaltext = "This\n\is\na\nline";
lines = originaltext.split("\n");
lines.sort();
joined = lines.join("");
