##Array 扩展

从数组制作以逗号分隔的字符串

var myArray = ["New York", "London", "Paris"]
myArray.toCommaString // New York,London,Paris

从数组中移除特定对象

var myArray = ["New York", "London", "Paris"]
myArray.removeObject("London") // ["New York", "Paris"]

检查数组是否包含特定对象

var myArray = ["New York", "London", "Paris"]
myArray.containsObject("London") // true
myArray.containsObject("Seattle") // false

获取特定对象的索引

var myArray = ["New York", "London", "Paris"]
myArray.indexOfObject("Paris") // 2

获取指定索引的对象，如果存在。

var myArray = ["New York", "London", "Paris"]
myArray.get(1) // London
