Multiline strings in JavaScript

Re:Multiline strings in JavaScript by wldlyinaccurate on Saturday July 12, 2014 @07:04AM (#8024237)

Probably worth pointing out that this won't play nice with most minification utilities unless you don't mind leaving all comments in the output.

I think for this reason I still prefer using Array.prototype.join for multiline strings:

    var str = [
        '<!doctype html>',
        '<html>',
            '<body>',
                '<h1>❤ unicorns</h1>',
            '</body>',
        '</html>',
    ].join('');

You can also

  var str = ' \
      <!doctype html> \
      <html> \
        <body> \
          <h1>❤ unicorns</h1> \
        </body> \
      </html> \
  '

I find it's better than string concat because the trailing \ is just one annoying thing rather than three.

6 months later:

    var str = ' \
        <!doctype html> \
        <html> \
          <body> \ 
            <h1>❤ unicorns</h1> \
          </body> \
        </html> \
    '

Help I'm maintaining your code and I get a syntax error

There is a space following one of the slashes.

... also this is (presumably) 'joined' at parse time, rather than runtime (and so only once per execution, guaranteed).

You can use the `/*@preserve` directive.

Hey, thanks - that'll teach me for not reading the full page!

Ooh I really really like this. Preserving newlines (one of the stated usecases for multiline) is dead easy too.

  var str = [
    //...
  ].join("\n");
