    Selecting items from an array multiple times


      Hi. I have an array that contains all the letters of the English alphabet plus a full stop and a space. What I wanted to do is to select randomly a large number of these letters and print them on the screen. My code this far is as follows:


      <script type="text/javascript">


        var letters = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L","M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", ".", " "];


         for (var i=0; i<=10; i++){


              var random_letter = Math.floor(Math.random()*28);


              var result=[];


              result[i] = [letters[random_letter]];







      When I run the above screen in Firefox I get this output:




      which includes 10 letters and a space. But, it also includes all those commas. Why is this happening? Am I doing something wrong with the code? Any help will be much appreciated.
