That's the point - how do you define small ?!?

If you can't do everything on the server, you have to perform some part
of the logic on the client. And the richer the client gets, the more
logic has to be performed on the client. Now you have the choice:

1. do the small part in JS - with the knowledge, that this part will
likely increase in the future
2. or look for an alternative language, which is as close to what you
are used to program as possible

My decision  is clear, after some hours hunting a bug, because i
declared a var "id" and somewhere made a test against "Id". I am using
the haxe to JS compiler, because its typesafe. If there were a pascal to
JS compiler, it would be an option to. But I doubt, that is feasible to
convert the libraries to work under that environment. And that's the
next problem. A language is only as good as its supporting libraries.
