Course of Refactoring Code Smells to Clean Code: Bloaters

💸 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 code is better than another? 🤔

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

Much has been written about the techniques to move from incomprehensible code to clean code. This is what we will see in terms of refactoring techniques to transition from Code Smells to Clean Code 😊

In this course, we are going to see how to put it into practice step by step with examples in multiple programming languages 🤟

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