简介
JavaScript是一种直译式脚本语言，它的一个很大的优势就是绝大多数浏览器都包含了JavaScript的解释器，这样我们在学习JavaScript时不需要安装任何开发软件，只要写一个网页文件，嵌入JavaScript代码就能在浏览器中进行代码的调试，非常方便。对于硬件爱好者来说，学习JavaScript还有一个好处就是能让自己的硬件作品更贴近IoT（物联网）应用。了解了JavaScript，我们能够在显示的页面上实现更多的效果，同时，目前有很多硬件也支持用JavaScript来编程。本书以制作国际象棋、五子棋、弹球、贪吃蛇、拼图、打飞机等经典游戏为例，带你从零起步，学习JavaScript的编程方法，适合对游戏和编程感兴趣的初学者阅读。而且本书融入了创客的项目式思路，在一个个实例的制作过程中学习知识，语言通俗易懂，图文并茂，会带给你与以往内容枯燥的编程教程完全不同的全新体验。
