Pass an array from ASP.NET(server) to javascript (client side)

I see many blogs asking a way to pass an array from server side to java script, most of them are unanswered or suggesting a ListBox (which is not simple). But to pass an array from server side to access it from client side we can use RegisterArrayDeclaration method.
 
Here is a simple example
 
In your code behind you can use the method like,

protected void Page_Load(object sender, EventArgs e)
{
    RegisterArrayDeclaration("MyArray", "'Welcome'");
    RegisterArrayDeclaration("MyArray", "'Hai'");
    RegisterArrayDeclaration("MyArray", "'Hello'");
    RegisterArrayDeclaration("MyArray", "'Best'");
    RegisterArrayDeclaration("MyArray", "'Super'");
}

You can access this array from client side Javascript code,

for (var i = 0; i < MyArray.length; i++) {
       alert(MyArray[i]);
}
