Intro

Refactoring is not here to modify the logic in your code. It does not target to improve performance of the application. It is used to improve readability and make it easier to maintain and add more features in the future.
The examples here are as straight forward and simple as possible because refactoring should be done by anyone, no matter their seniority level.
