    <script type="text/javascript" language="javascript">

      

        //SIMPLE. Output is "1 2 3 4 5".

        i=0;

        while(i<=4){

          i++;

          window.alert(i);    

        }

   

        //BREAK.  Output is "1 2" since we break out of for loop before condition i<=4 is reached.

        i=0;

        while(i<=4){

          i++;

          if(i==3) { break; }

          window.alert(i);

        }

   

        //CONTINUE. Output is "1 2 4 5" since display of number 3 is skipped.

        i=0;

        while(i<=4){

          i++;

          if(i==3) { continue; }

          window.alert(i);

        }

            

    </script>
