Description

The course deals with the concept of refactoring as a way of preventing software rot. The course describes various smells indicating that a code needs refactoring, explains which refactoring types best suit specific situations, and describes the work of refactoring in detail through analyzing concrete real-life cases.

Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure. It is a disciplined way to clean up code that minimizes the chances of introducing bugs. In essence when you refactor you are improving the design of the code after it has been written.

The need for refactoring is provided by the so-called "smells" that may signal problems inside the code. Smells may be found at the level of one class or between classes.

Refactoring principles apply to any object-oriented programming language.
