hi im johan Mortensen I would like to share a trick or two about simplifying conditional logic heres a really ugly piece of code from the gilded Rose kata with some particularly complex conditional logic um the main trick is best shown by exposing the problem heres a piece of business logic we increment quality up until 50 and never above we can extract that quality to a method but it doesnt encapsulate all of that incrementation project this is the same piece of logic and it didnt get a captured idea in the method I extracted so well have to think of something more intricate and this is where the trick comes in I can remove this if statement if I add the close to around every in underlying instruction like so now lets remove it and this is equivalent code by the way the tests tell me that that is so now heres the same statement twice I can remove one of them and I can extract this too and this time this part gets extracted the next part of this method is this piece why do you
