The Array object is used to store a set of values in a single variable name.
阵列(数组)对象用来在一单独的变量名称内存储一系列值。

Defining Arrays
定义数组

The Array object is used to store a set of values in a single variable name.
数组对象被用来存储值（在单一的变量名称中）

We define an Array object with the new keyword. The following code line defines an Array object called myArray:
我们通过“new”关键字来定义一个数组对象。下面的代码行定义了称为myArry的数组对象：

var myArray=new Array()

There are two ways of adding values to an array (you can add as many values as you need to define as many variables you require).
有两种方法来添加数组值（你可以添加你所需要的值并定义你所想要的变量名称）

1:

var mycars=new Array()
mycars[0]="Saab"
mycars[1]="Volvo"
mycars[2]="BMW"

You could also pass an integer argument to control the array's size:
还可以通过引入一个整数来控制数组的大小：

var mycars=new Array(3)
mycars[0]="Saab"
mycars[1]="Volvo"

mycars[2]="BMW"

2:

var mycars=new Array("Saab","Volvo","BMW")

Note: If you specify numbers or true/false values inside the array then the type of variables will be numeric or Boolean instead of string.
注意：如果你在数组里指定数字或真/假值那么变量的类型将变为数字型或布尔型替换了字符串型

Accessing Arrays
访问数组

You can refer to a particular element in an array by referring to the name of the array and the index number. The index number starts at 0.
你可以指示数组的名称和索引数字来从数组中提出一个单独的元素。索引数字从0开始。

The following code line:
正如下面的代码行：

document.write(mycars[0])

will result in the following output:
将有下面的输出结果：

Saab

Modify Values in Existing Arrays
修改现有的数组值

To modify a value in an existing array, just add a new value to the array with a specified index number:
要修改现有数组的值只需要通过添加指定索引数字里的值

mycars[0]="Opel"

Now, the following code line:
现在，下面的代码行：

document.write(mycars[0])

will result in the following output:
现在，下面的代码行：

Opel
