I have started to read the Clean code book by Robert C Martin ( https://www.amazon.fr/Clean-Code-Handbook-Software-Craftsman ship/dp/0132350882)

In the introduction of this book, the author present definition of "clean code" from view point of Multiple well known programmer :
-Bjarne Stroustrup
-Grady Booch
-Dave Thomas
-Mochael Feathers
-Ron Jeffries
-Ward Cunningham
(of course, all definition tend to cross each other in some point)

So, here come my post, I'm really interested in knowing the clean code definition of people who have made Upp (I want to know your point of view Mirek !)
It would be really interesting if you people all share your definition of clean code ! Also , what would be the most important advise you would give to someone who want to write a better/clean code ?

Thanks for your participation
Best regard
