Getting the number $# is slow.

There is no reason why bash has to be slow. Javascript was slow. But
it has been optimized to be much faster than it was before.

What I see bash is that it is syntax is much better than other
languages in terms of interactive use and not use () for arguments? It
could be made faster and with some additional features, it could be
used for other more serious applications rather than just a glue of
other tools.
