Summary:

Prefactoring approaches software development of new systems using lessons learned from many developers over the years. It is a compendium of ideas gained from retrospectives on what went right and what went wrong in development. Some of these ideas came from experience in refactoring. Refactoring is improving the design of existing code to make it simpler and easier to maintain. This practical, thought-provoking guide details prefactoring guidelines in design, code, and testing. These guidelines can help you create more readable and maintainable code in your next
