I have learned clean code and some people advise me to learn refactoring. So what are the best resources to learn refactoring and code smells in practical way? I tried to learn from Martin Fowler book Refactoring improving the design of legacy code 2nd edition but in code smells chapter he doesn't explain the smells in code like uncle bob in clean code.
Note I have some experience in TDD and clean architecture.
The resource I've used the most is Refactoring Guru, it contains a list of code smells and refactoring techniques and how/when to apply them.
