Hello,

  I noticed that js-mode includes the keyword "transient" in its list of
javascript keywords.  I can't find a reference anywhere that confirms
this is a real javascript keyword.  Is it there in error?

Running js-mode version 9, dated 2009-07-25 in emacs 23.2.1.

Thanks.

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.

I found that Mozilla warns if you try to use "transient" as a variable
name.  So nevermind, it does belong.
