Make a Javascript calculator for any notation not already in the calculator. The calculator must have an option to evaluate one step at a time. The notation implemented must be able to outpace any primitive recursive function. (Exceptions may be granted, for example, traditional notation only goes to FGH 2, but will be allowed.) Send CatsAreFluffy a link to your calculator's source code once you are done.
