Clean Code in JavaScript
內容描述
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.

James Padolsey is a passionate JavaScript and UI engineer with over 12 years' experience. James began his journey into JavaScript as a teenager, teaching himself how to build websites for school and small freelance projects. In the early years, he was a prolific blogger, sharing his unique solutions to common problems in the domains of jQuery, JavaScript, and the DOM. He later contributed to the jQuery library itself and authored a chapter within the jQuery Cookbook published by O'Reilly Media. Over subsequent years, James has been exposed to many unique software projects in his employment at Stripe, Twitter, and Facebook, informing his philosophy on what clean coding truly means in the ever-changing ecosystem of JavaScript.
