内容提要

  

    Angular 2能够帮助你构建出更快、更有效、更灵活的跨平台应用。它解放了JavaScript的开发，使代码变得更有组织、可读性更好、经受得住测试。
    钱德玛尼·阿罗拉、凯文·汉尼斯著的《Angular2实例(影印版)(英文版)》先后构建了三个复杂度不一的应用。首先是一个简单的猜数字游戏，它作为将你带入Angular世界的一个平台。接下来，你将学习编写一个流行的7分钟锻炼(7 Minute Workout)应用。其中涉及了Angular的构建块。最后的一个个人助理教练(Personal Trainer)应用将已经编写好的7分钟锻炼应用修改成了一个全功能的个人健身及跑步工具，其中涉及了高级指令，这是Angular最基本也是最强大的特性。
    除此之外，你还将学到Angular所提供的测试工具以及框架，可用于有效地测试应用。在最后，书中给出了一些实用建议和有用的技巧。在你使用Angular构建更多的应用时，它们会助你一臂之力。
