Beautiful JavaScript

Beautiful JavaScript (originally published by O'Reilly Media) is an essay collection written by a group of experts in front-end and JavaScript, edited by Anton Kovalyov. The simplified Chinese edition was published by China Electric Power Press in December 2017, translated by Du Chunxiao and Si Weiwei. The book has 14 chapters, each written by a different author and centered on a specific technical or conceptual theme: one starts from prototypes and inheritance to discuss how mixins can replace traditional class-based inheritance for code reuse; another examines the entanglement between eval and domain-specific languages, distinguishing its legitimate uses and risks in scenarios such as template compilation, multi-language mixing, and binary pattern matching; still another begins with a seemingly playful topic like how to draw a bunny to explore the diversity of expressive forms and the pedagogical value of code style. The book also covers style conventions in team collaboration, identity and environment models in constructor design, writing a parser and evaluator for mathematical expressions in JavaScript, the evolution of the Backbone framework, error handling across browsers and Node.js, the Node.js event loop and asynchronous non-blocking I/O, and functional programming in JavaScript. The book does not aim to be a syntax manual but treats language features as expressive tools: why a language born in haste can keep evolving and dominate the Web for so long, while many more orderly designs have faded to the margins. The chapters are short and varied in perspective, suited to readers who have mastered basic syntax and want to broaden their aesthetic and engineering judgment about JavaScript.
