    Message 1 of 4 , Dec 22, 2009
      I have found the following style construct:

      var htmlstring;

      ...

      htmlstring
      = '<h1>Title</h1>'
      + '<p>'
      + 'Some text'
      + '</p>'
      ;

      preferential for at least two reasons:

      1) When you use a compressor, like YUICompressor (you /are/ compressing your
      code, right?), the string is concatenated for you, so this actually takes up
      less space than the escaped carriage returns; and

      2) It is more readable without a performance penalty, as indentations are
      stripped during compression.

      Cheers, Mike

      A good point well made, and yes we re using YUICompressor. Cheers, James.
