Hello all! I'm in the beginning stages of learning javascript and have a very simple problem. It's so simple that I'm nearly embarassed to ask it. I'd like to add a carriage return to the following alert:

Code:
alert("Hello World. How are you?")
My desired output is:

Hello world!
How are you?
After hours of searching, I can't seem to find the correct syntax to do this. Any help with this is much appreciated. Thanks in advance.
