下面的例子中，通过数组下标遍历数组元素，并把每个元素的值修改为原值的2倍。

-
var numbers = [1, 2, 3, 4, 5];
-var length = numbers.length;
-for (var i = 0; i < length; i++) {
-  numbers[i] *= 2;
-}
-// 遍历后的结果 [2, 4, 6, 8, 10]
+
var numbers = [1, 2, 3, 4, 5];
+var length = numbers.length;
+for (var i = 0; i < length; i++) {
+  numbers[i] *= 2;
+}
+// 遍历后的结果 [2, 4, 6, 8, 10]

截断数组

下面的例子中，如果数组长度大于 3，则把该数组的长度截断为 3 。

-
var numbers = [1, 2, 3, 4, 5];
+
var numbers = [1, 2, 3, 4, 5];
 
-if (numbers.length > 3) {
-  numbers.length = 3;
-}
+if (numbers.length > 3) {
+  numbers.length = 3;
+}
 
-console.log(numbers); // [1, 2, 3]
-console.log(numbers.length); // 3

+console.log(numbers); // [1, 2, 3]
+console.log(numbers.length); // 3
