Is there a newline character in javascript?

[sublimity]

I'm trying to use a mailto action in a form. In the process of trying to get IE to produce body text, I am writing a function in javascript that will produce the body text for the email using variable values for the form data. Is there a newline character that javascript uses that will create a new line in the browser's body portion of the email?

As in

document.write('This is line 1.\nThis is line 2.');
