Confusion is part of programming. When you learn a new programming language, concept, or framework, the new ideas might scare you. When reading unfamiliar code or code that you wrote a long time ago, you might not understand what the code does or why it was written the way it was. Whenever you start to work in a new business domain, new terms and jargon can all bump into each other in your brain.
It’s not a problem to be confused for a while, of course, but you don’t want to be confused for longer than needed. This chapter teaches you to recognize and decode your confusion. Maybe you’ve never thought about this, but there are different ways to be confused. Not knowing the meaning of a domain concept is a different sort of confusion than trying to read a complicated algorithm step by step.
