Hi, sorry your patch was overlooked for so long.  Unfortunately, I think
just adding keywords to js--keyword-re will not quite do the right
thing, based on https://debbugs.gnu.org/cgi/bugreport.cgi?bug=31306#5:

    Specially, "as" and "from" should only be highlighted in an import
    statement. "of" should only be highlighted in a for statement. Any other
    occurrances of "as", "from" and "of" should not be highlighted as they
    are legal identifiers outside of import and for statements respectively.
