It appears the language has changed.  According to
http://bclary.com/2004/11/07/#a-7.5.3, "transient" is a future reserved
keyword.  However, the official specification at
http://www.ecma-international.org/publications/files/ecma-st/ECMA-262.pdf reserves
a smaller set of keywords.  If these keywords do actually work correctly
in modern Javascript implementations, we should remove them from js-mode.
