To my understanding, all of your JavaScript gets merged into 1 file. Rails does this by default when it adds //= require_tree . to the bottom of your appl
I haven't tried this out, but it looks like the following is true:
if you have a content_for that is javascript (e.g. with real javascript within it), sprockets would not know about it and thus this would work the same way as it does now.
if you want to exclude a file from the big bundle of javascript, you would go into config/sprockets.yml file and modify the source_files accordingly. Then, you would just include any of the files that you excluded where needed.
