How to work with Javascipt Array

    Array is a very powerful concept in any programming language. It can strore same or any kind of object data in its elements.
    In his post I tried to venture my learning on storing and displaying array elements in Javascript.
    Storing a javascript array elements can be divided into two parts..

    Static:

    Ads code goes here
    <SCRIPT language = “JavaScript”>
    <!– Begin Hiding JavaScript
    cities = new Array(5);
    cities[0] = “Hyderabad”;
    cities[1] = “Kolkata”;
    cities[2] = “Delhi”;
    cities[3] = “Mumbai”;
    cities[4] = “Panaji”;
    </script>

    Dynamic:

    <SCRIPT language = JavaScript>
             var elements= prompt(“Enter How Many elements”, “Elements”);
             cities = new Array(elements);
     for(var i=0;i<=(elements-1);i++)
    {   
       var cities[i]= prompt(“Enter your city Name”, “City”);
    }
     </SCRIPT>

    Now to display those elements there are 3 ways:
    One traditional for loop–
    first find out the length of the array—

    len=cities.length();
    for(i=0;i<=len-1;i++)
    {
    document.write(cities[i]+”<BR>”);
    }

    Second method could be more static

    document.write(cities[0]+”<BR>”);
    document.write(cities[1]+”<BR>”);
    document.write(cities[2]+”<BR>”);
    document.write(cities[3]+”<BR>”);
    document.write(cities[4]+”<BR>”);



    The Third method could be—

    join_crit =  cities.join();
    document.write(join_crit);

    I like this method to display all the elements of an array.
