Content introduction:

This book is a new edition of the classic "Reconstruction" 20 years after its publication. The book clearly reveals the process of refactoring, explains the principles and best practices of refactoring, and gives when and where to start digging code for improvement. More than 60 feasible refactorings are given in the book, and each refactoring introduces the motivation and technology of a proven transcoding technology. The refactoring standards proposed in this book will help developers modify the code one small step at a time, thus reducing the risks in the development process.
