Livescript, How to end a unnested callback?

Question

Reffering to: http://livescript.net Unnested callbacks and parentheses free chaining: LiveScript

<-! $ 'h1' .on 'click'
alert 'boom!'

JavaScript

$('h1').on('click', function(){
  alert('boom!');
});

How can I write livescript like this in Javascript?

JavaScript

$('h1').on('click', function(){
  alert('boom!');
});
alert('out of callback');

Answer 1

You can't. That's backcall.

You have two options : use a do (I don't think it makes sense)

do
  <- $ 'h1' .on 'click'
  alert 'boom!'

... Or just use a callback ?!

$ 'h1' .on 'click' ->
  alert 'boom'
