[chuck-users] Extending the software ??

Hello, I am Maria, I have been studying for some time at the University of Systems Engineering, and I have programmed some java and common lisp, in addition to C. I understand that SuperCollider and ChucK are open source environments, so I can extend mathematical algorithms, to compose algorithmically, but according to this: Which programming language is best suited to SuperCollider? Which programming language is most suitable for ChucK? ,Maria.
