This time I'll introduce Object-Oriented UI. What is Object-Oriented UI? For people who want to learn about UI design patterns, I hope this can be helpful (^^)
I'll explain "extracting unrelated subproblems" in an intuitive way. For people who don't understand what subproblems mean and want to grasp the concept of extracting unrelated subproblems through imagery. I hope this helps with understanding the book Readable Code.
