In this code snippet we will learn about JavaScript Arrays.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

    <title></title>
</head>
<body>
    <script id="javascript">
        var color = [];

        color[0] = "Red";
        color[1] = "Blue";
        color[2] = "Green";

        alert("You choose :" + color[1]);
    </script>
</body>
</html>

Another Pattern

var color = ["Red", "Green", "Blue"];
alert("You choose :" + color[1]);

Output

Another Example

function addColor()
{
    var temp = "";
    for (var i = 0; i < arguments.length; i++)
    {
        temp += arguments[i] + " ";
    }
    return temp;
}
var colorList = addColor("Red", "Green", "Blue");
alert(colorList);
