Are there big systems written in JS?
All Mozilla products.
Mozilla products are in C++. Only the GUI is scripted in JS (XUL). And handling GUI events is not high-performance computing in my book ;)
I don't think anybody can seriously think that Javascript performance can ever beat what CMUCL/SBCL can do to Lisp code that is declared through and doesn't use CLOS (plus assorted other techniques). And even if so, if a certain somebody would finish the LLVM backend for SBCL then it's easy picking :-)
I completely agree.
