Introduction
Computer books
The consistency of the encoding style must be emphasized in any language. As long as it is developed by a team, it is critical that everyone write code in the same way. In this way, you can easily understand and maintain the code of the other party.
Compiling maintainable JavaScript explains how to compile highly maintainable JavaScript code in team development. The book details how to write JavaScript as a team member. This book covers the coding style, programming skills, automation, testing, and other aspects, including the introduction of specific styles and principles, as well as examples and tips, finally, we also introduced how to use automated tools and methods to achieve a consistent programming style.
Nicolas C. zakas, author of "Compiling maintainable JavaScript", is a top-level Web technical expert and author of "Advanced JavaScript programming. He used to be Yahoo! The chief front-end development engineer, after finishing the transformation from a "Lone hero" to "Team elites", he extracted many best programming practices from the perspective of front-end engineers, these include the best rules that many industry authorities advocate, and these valuable experiences are the core content of this book.
Compiling maintainable Javascript is suitable for front-end development engineers, JavaScript programmers, and readers who want to learn JavaScript programming. It is also suitable for developers and project owners. Using the techniques and techniques described in this book, JavaScript team programming can be achieved from the haze of Chivalrous personal preferences, to the real high maintainability, high efficiency and high level.
