          console.time('programming Logic And Code');

            // for  processing 
          alert('Click to continue'); 

              // for measuring the time and closing
          console.timeEnd('programming Logic And Code');

               // for  processing

                alert('One more time'); 

          

                // for measuring the time and closing

           console.timeEnd('programming Logic And Code');

var     element_programming_logic_code = document.getElementsByTagName('*'); 

//select all elements on the page

console.time('Loop_time_programming_logic_and_code');

         for (var i = 0; i < 5000; i++) 

              {    

                     for (var j = 0, length = element_programming_logic_code .length; j < length; j++) 

                         {       

                               // nothing to do ...   

                         }
