The most popular refactoring books Christian (Tech Agile Coach at Eficode) has read certainly provide a lot of knowledge, but they are not easily digestible. He wrote the “Five Lines of Code”, a book that would ease the reader into refactoring, giving some more practical perspectives and some good advice on how to do things, making refactoring more accessible.
