a snippet to have multi lines string in javascript.

multiline.js

var multilineString	= (function(){ /*
  this
  is
  a
  multiline
  string.
*/}).toString().split('\n').slice(1, -1).join('\n');

console.log(multilineString);

It does not work if inside the comment has the <script></script> tag

For me it worked good. I want it to have PGN chess games into a javascript variable. For sure having html tags, javascript, or php inside the string will cause problems, at least that you add the logic to escape them. For everything rest, this is good. Thanks for sharing.
