What will I learn?

Clean Code with JavaScript Course shows you how to spot code smells, apply clean code principles, and refactor without breaking behavior. You will design clear functions and data models, structure modules, and write small, testable pricing and calculation utilities. Learn practical refactoring patterns, automated testing, and lightweight documentation so your JavaScript codebase stays readable, reliable, and easy to extend.

What our students say

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without needing to switch platforms... I appreciate everything you do, I've already recommended you to others...

I like how the lessons are straight to the point and how I can switch chapters and skip content I don't need.
