If I read syntax/javascript.vim correctly you need to enable syntax
based folding by setting :let javaScript_fold=1 in e.g. your .vimrc.

However there seems to be a bug with syntax based folding, which
prevents folding. The following patch works for me (I understand syntax
rules only very basically), therefore cc'ing the maintainer Claudio
Fleiner.

The problem seems to be that the syntax keywod javaScriptType
takes precedence over the defined region javaScriptFunction and
therefore prevents that the syntax folding applies. Claudio probably
knows better if this is true and how to fix the problem.
