What will I learn?
Clean Code with JavaScript Course teaches you to identify code smells, apply clean code principles, and refactor without breaking behaviour. 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 remains readable, reliable, and easy to extend.

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