angularjs api
api 意为 application programming interface（应用程序编程接口）。
angularjs 全局 api
angularjs 全局 api 用于执行常见任务的 javascript 函数集合，如：
比较对象
迭代对象
转换对象
全局 api 函数使用 angular 对象进行访问。
以下列出了一些通用的 api 函数：
| api | 描述 |
|---|---|
| angular.lowercase() | 转换字符串为小写 |
| angular.uppercase() | 转换字符串为大写 |
| angular.isstring() | 判断给定的对象是否为字符串，如果是返回 true。 |
| angular.isnumber() | 判断给定的对象是否为数字，如果是返回 true。 |
angular.lowercase()
