Rbjs is a Ruby DSL that translates 1-to-1 into Javascript

It integrates with Rails 3.1 and 4, and Sinatra

What?

Instead of this (create.js.erb)

<% if @collection %>
  jQuery(<%= j render(@image) %>).appendTo('<%= dom_id @collection %>').hide().show('slide')    
<% else %>
  jQuery(<%= j render(@image) %>).insertAfter('.dropzone').hide().show('slide')
<% end %>

you can write this (create.js.rb)

if @collection
  jQuery(render @image).appendTo(dom_id @collection).hide!.show('slide')    
else
  jQuery(render @image).insertAfter('.dropzone').hide!.show('slide')
end

Why?

Why not?
