Foundations of Programming: Refactoring Code

Take existing code and make it better—more readable, efficient, understandable, and updateable—with refactoring.Refactoring is the process of taking existing code and improving it. While it makes code more readable and understandable, it also becomes much easier to add new features, build larger applications, and spot and fix bugs. In this course, staff author Simon Allardice introduces the formalized, disciplined approach to refactoring that tells you exactly what to look for in your code, and how to fix it, through a series of "code smells"—clues that let you look at a block of code and realize when there's something wrong with it. Topics include: What is refactoring? Recognizing common code smells Simplifying method calls Making conditions easier to read Using refactorings at the method, class, and application level
