JavaScript functions can be variadic, so there is no well to tell in that case.
However, for normally defined javascript functions that name their
parameters, you can access the length parameter on the function. For
example
function blah(a, b, c) { }
print(blah.length); // Prints 3.
If you are defining the function on the C++ side, then you should set
the appropriate length.
