The actual architecture of the FORTH, Scheme and (older generation) TCL interpreters are archaic. You've got a lexical analyzer, but not a parser, and generally not a bytecode interpreter in the traditional sense. More recent TCL versions have moved in the bytecode direction to improve performance, but classic TCL was essentially LISP with lists implemented as space-separated strings. Javascript is basically an ALGOL-type language with a conventional implementation, but it certainly radical in quite a few ways. Personally I miss ECMAScript 4; I would have liked to have seen a Javascript-like language with stronger typing, better IDE support and more support for programming in the large. It would be appealing to have a programming environment where we could share code on the client and the server, even if it would be a terrible temptation for people to make mistakes Well, it all depends on how you define “exotic.”

Which is a shame.

Javascript is an exotic dynamic language–but this fact has been carefully concealed. Which is a shame.
