如果不引人注目的javascript的原则表明我们需要将表现与行为分开，为什么可以通过像ng-click = archive()这样的代码来实现角度最佳实践？
Adherents to “Unobtrusive JavaScript” argue that the purpose of markup
is to describe a document’s structure,not its programmatic behavior
and that combining the two negatively impacts a site’s
maintainability.
可用性不相关，因为没有人看到您的DOM代码，除了您的开发团队。一旦您拥抱角色哲学，内联事件处理程序就更容易维护。虽然，您可以随时使用$watch来保持您的HTML清洁。
正如Angular网站最好的，
@H_301_13@AngularJS lets you extend HTML vocabulary for your application. The
resulting environment is extraordinarily expressive,readable,and
quick to develop.
搜索引擎可能对您的网站进行索引稍微困难一些，但是我们有RSS，Sitemaps和AJAX Crawling来解决这个问题。
除非您为非智能手机市场构建应用程序，否则优雅的降级不再相关。几乎所有用户都在支持现代JavaScript(带垫片)的浏览器上。
辅助功能和角度不冲突。只需确保使用ARIA标签和正确的标记。角度使得编写可测试代码变得更加容易，内置于exception handling。
如果您使用功能污染全球范围，则分离问题是一个问题。角度使得更容易在不影响其他文件或代码的情况下分别维护javascript代码。
