How to Find the Stinky parts of your Code

#codenewbie #tutorial #codequality #beginners

TL;DR: A Compilation of bad smells in code.

The code smells badly.

Let's see how to change the aromas.

In this series, we will see several symptoms and situations that make us doubt the quality of our development. We will present possible solutions.

Most of these smells are just hints of something that might be wrong. They are not rigid rules.
