What would I recommend learning?
- C
- Prolog
- Erlang (I’m biased)
- Smalltalk
- Javascript
- Hakell / ML /OCaml
- LISP/Scheme/Clojure
A couple of years should be enough (PER LANGUAGE).
Notice there is no quick fix here - if you want a quick fix go buy “learn PHP in ten minutes" and spend the next twenty years googling for "how do I compute the length of a string”
