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');

search 'callback' in the livescript.net , and you can find what I'm talking about. — Lhfcws, Mar 29 '13 at 18:11

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'

Well, thx, now I'm using the second solution. and one more question , what's the difference between callback and backcall? :) – Lhfcws Mar 30 '13 at 06:22
Callback is forward `->` and backcall is backward `<-` – Ven Mar 30 '13 at 10:56

that worked for me @ Livescript 1.2.0

(
<- $ 'h1' .on 'click'
alert 'boom!'
)
(
<- $ 'h2' .on 'click'
alert 'kaboom!'
)

Enjoy)
