So looks like the area of java applets are over, less and less browsers support them I think? Some of my java applet option calculators where running for about 20 years, until very recently without any maintenance, that is rather robust I must say, but looked horrible old fashioned in the end. When I built them I expected them to max last about 2 years.
so what is the new tools to make online option calculators now?
Java script was not good back then and not now?
google sheets?
Can python be used online? like a java applet or so?
