Refactoring involves modifying the structure of code without changing its behavior to improve readability and maintainability. Key lessons include analyzing the code beforehand, refactoring as a team, composing smaller methods, simplifying conditional expressions, ensuring code understanding, setting clear objectives, making incremental changes, and considering performance. The goal is to maintain an efficient and manageable codebase.

Code Refactoring: 10 Lessons I Learned on Improving Code

<ol start="4">
<li>Simplifying Conditional Expressions
﻿In this one you are not really simplifying, just changing the if-else with ternaries.
﻿You could pass all that to a function and use early returns without the if-else that are really what makes it complex. Having a chain of if-else even if its ternary turns the code complex to read.
﻿Even better, you could use strategy pattern if it applies</li>
</ol>

He complicated the code more than needed in the 4) Simplifying Conditional Expressions section. The former, if/else clauses were more readable than the spaghetti ternaries :D

I would add to perform Refactoring along with performing unit tests. Because if you do refactoring without unit test, you risk introducing new bugs.

Thank you for sharing this amazing article. As a new developer, I found it very helpful.
