 - 通过索引访问数组元素

-const first = fruits[0]
-// Apple
-const last = fruits[fruits.length - 1]

+<!-- UTSJSON.Array.sampleVisit.test -->
 - 遍历数组
-```ts
-fruits.forEach(function(item, index, array) {
-  console.log(item, index)
-})
-// Apple 0
-// Banana 1

 - 注意：数组遍历不推荐使用 for in 语句，因为在 ts 中 for in 遍历的是数组的下标，而在 Swift 和 Kottlin 中遍历的是数组的元素，存在行为不一致。

 ### 访问数组元素
 
 数组的索引是从 0 开始的，第一个元素的索引为 0，最后一个元素的索引等于该数组的 长度 减 1。

 如果指定的索引是一个无效值，将会抛出 IndexOutOfBoundsException 异常
 
 下面的写法是错误的，运行时会抛出 SyntaxError 异常，而原因则是使用了非法的属性名：
-
 ```ts
 console.log(arr.0) // a syntax error
