Old code. Ugly code. Complicated code. Spaghetti code. Jibberish nonsense. In two words, Legacy Code. This is a series that will help you work and deal with it.

Unfortunately, we live in a reality that is not ideal. We have to understand, modify and enhance ages-old code. We have to work with legacy code. So what are you waiting for? Let's get our heads into this first tutorial, get the code, understand it a little bit and create a safety net for our future modifications.
