Code smell

Code smell is like a bad smell that comes from something. In programming, when you write a piece of code, sometimes it can have a bad smell. A bad smell in code usually means that the code is not organized well, it is hard to understand or it takes a long time to execute. When you have code with a bad smell, it can be hard for other people to understand what it does and it can take a long time for the code to run. It is best to try to fix the code smell to make the code more readable and easier to use.
