Hello Friends,

I went through the learning material on jQuery Site.  http://learn.jquery.com/using-jquery-core/iterating/. Here we have an nice example on iteration as pasted below. 

  

   

    $( "input" ).each( function( i, el ) {
   
  
  

   

     var elem = $( el );
   
  
  

   

     elem.val( elem.val() + "%" );
   
  
  

   

    });
    

    If we see, $("input") is a jQuery object and if we are doing .each on it , 
    each element returned will be a jQuery object , i mean el here. 
    Then why do we wrap it again with $() to make it jQuery object. 
    

    Thanks
