These two methods work, too: ['this string', 'spans multiple', 'lines'].join('\n'); 'this string\n' + 'spans multiple\n' + 'lines' The second one is better because the yuicompressor will be smart enough to squish it all into a single string literal, so you don't have the run-time overhead of the join operation. Escaping linebreaks is a pretty bad idea, imo. If you have a trailing space after the \, then it’s a syntax error.

These two methods work, too:

['this string',
'spans multiple',
'lines'].join(’\n’);

‘this string\n’ +
’spans multiple\n’ +
‘lines’

The second one is better because the yuicompressor will be smart enough to squish it all into a single string literal, so you don’t have the run-time overhead of the join operation.
