Course of Refactoring Code Smells to Clean Code: Change Preventers

💸 First lesson available without registration 💸

What you will learn in this Refactoring and Clean Code course

Is code quality something measurable? How can we decide if one piece of code is better than another? 🤔

In this course, you will learn to objectively identify aspects that make your code hard to maintain, and most importantly, what processes to apply to improve it.

Much has been written about the techniques to go from incomprehensible code to clean code. This is what we will see in terms of Refactoring techniques to transform Code Smells into Clean Code 😊

In this course, we will see how to implement it step by step with examples in multiple programming languages 🤟

Achieve quality programs by applying good practices of refactoring and clean code 💪
