Javascript syntax folding

[Tobia]

How can I enable syntax folding in Javascript files?

The syntax file seems to support it, controlled by a variable named
javaScript_fold, but setting it in my vimrc or on the command line
doesn't seem to do anything:

        let javaScript_fold=1

        vim -u /dev/null +"let javaScript_fold=1" file.js

What am I doing wrong?
