If I understand what you're getting at, you can find some answers here.... Multiline strings in Javascript

You could use ejs or http://jade-lang.com/ as a templating engine. JavaScript doesn't natively support multiline strings unless you want to escape the line breaks.

var str = "some text \
Some more text";
