Overview of this book

Building robust apps starts with creating clean code. In this book, you’ll explore techniques for doing this by learning everything from the basics of JavaScript through to the practices of clean code. You’ll write functional, intuitive, and maintainable code while also understanding how your code affects the end user and the wider community. The book starts with popular clean-coding principles such as SOLID, and the Law of Demeter (LoD), along with highlighting the enemies of writing clean code such as cargo culting and over-management. You’ll then delve into JavaScript, understanding the more complex aspects of the language. Next, you’ll create meaningful abstractions using design patterns, such as the Class Pattern and the Revealing Module Pattern. You’ll explore real-world challenges such as DOM reconciliation, state management, dependency management, and security, both within browser and server environments. Later, you’ll cover tooling and testing methodologies and the importance of documenting code. Finally, the book will focus on advocacy and good communication for improving code cleanliness within teams or workplaces, along with covering a case study for clean coding. By the end of this book, you’ll be well-versed with JavaScript and have learned how to create clean abstractions, test them, and communicate about them via documentation.

Enemy #4 – The cargo cult

In the early 20th century, it was observed that some Melanesian cultures would carry out rituals that would emulate Western technologies and behaviors, such as building runways and control towers out of wood and clay. They were doing this in the hope that material wealth, such as food, would be delivered to them. These odd rituals arose because they had previously observed cargo being delivered via Western planes and falsely concluded that it was the runway itself that summoned the cargo.

Nowadays, within programming, we use the terms cargo cult or cargo culting to broadly describe copying patterns and behaviors without fully understanding their true purpose and functionality. When programmers search for a solution online and copy and paste the first piece of code they find without consideration as to its reliability or safety, they are partaking...
