Can you please update the answer? It's 2015 now and JavaScript has multiline strings – mikemaccana Oct 11 '15 at 21:44

I think I discovered another way to do it inline without any invasive syntax on every line. Use Javascript's ability to convert a function to string and create a multiline comment with the /**/ syntax then remove the "function() {/*\n" and "\n*/}".

var multiline = function(string) { return string.toString().replace(/(^[^\n]*\n)|(\n\*\/\})/g, ""); };

console.log(multiline(function() {/*
Hello world!
I'm a multiline string!

Tada!
*/}));

The only pitfall I can see in this is the syntax highlighting.

EDIT: Had I scrolled down a little more, I would have seen this answer doing exactly the same thing: http://stackoverflow.com/a/5571069/916553

It's not extremely elegant but it's clean enough for me:

var myString = "First line" + "\n";
var myString = myString + "Second line" + "\n";
var myString = myString + "Third line" + "\n";

You should use var myString += "Second line \n"; instead. MUCH cleaner. – Colin Feb 27 '13 at 4:45

Actually, you should use myString += "Second line \n"; The var shouldn't be repeated. – Michael Mior Jul 11 '13 at 14:04

use + only for concatenate strings. Not need declare all buffer for each line. Its horrorific. – e-info128 Aug 2 '13 at 15:43

Should I correct my answer or should I leave it there as a good example of how NOT to do things? If it's best for the people who learn JavaScript, I don't mind leaving it there as it is now. A few negative points can't hurt that much. – Bear Bear Nov 26 '14 at 1:04
    
I would suggest removing it... – Druzion Jan 28 at 14:44
