Organizing code

Module introduction

Introduction

In this module you'll learn how to shape your code so it remains readable, resilient, and easy to evolve — a foundational skill for any web developer. Organizing code isn't just about neat folders and filenames; it's a discipline that improves maintainability by making intent clear, accelerates team collaboration through consistent patterns, and ultimately enhances the user experience by reducing bugs and enabling faster iteration. Throughout Module 3 we'll explore practical techniques such as modular file structure, component-based design, naming conventions, CSS organization strategies (including practical patterns), and essential tooling like linters, formatters, and simple build steps. By the end you'll be able to structure projects that scale with confidence, onboard teammates faster, and deliver more reliable interfaces to users.
