Oh, STL will with certainty have better performance. My thought was, that for at least a small script, a thrown-together Javascript table would have a smaller memory footprint than the penalty associated with including STL at all in your program.
I'm recalling now that Google had released a template library for hash tables a few years back with an ultra-low memory footprint. I guess I'll check that out.
