商品描述

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.

  • Understand the true purpose of code and the problems it solves for your end-users and colleagues
  • Discover the tenets and enemies of clean code considering the effects of cultural and syntactic conventions
  • Use modern JavaScript syntax and design patterns to craft intuitive abstractions
  • Maintain code quality within your team via wise adoption of tooling and advocating best practices
  • Learn the modern ecosystem of JavaScript and its challenges like DOM reconciliation and state management
  • Express the behavior of your code both within tests and via various forms of documentation
  • Write maintainable JS code using internal abstraction, well-written tests, and well-documented code
  • Understand the agents of clean coding like SOLID principles, OOP, and functional programming
  • Explore solutions to tackle common JavaScript challenges in building UIs, managing APIs, and writing states
