It may be a matter of explaining it differently. Maybe just the names! But I never "got" MVC, and I got the one way data flow pattern straight away. Maybe I was just old enough to get the point that time around.
I'm glad I'm not the only one that doesn't get MVC. I can sort of understand it if I study a real example for a long time, but to doesn't stick.
Sometimes I want to think that learning to code in the days of 8-bit computers is somehow incompatible with a lot of modern programming concepts, but maybe I'm just old and tired.
