this is a comment page of a school curriculum grading system. I want to do this: 
 1. Count the number of words in each comment 
 2. When the whole loop is over, count out the total number of words of all comments 
 < div id= "header" > 
 < H1 > Course Rating Information < / H1 > 
 
 
  Number:  
 <% = @ course.number% > 
 
 
  Year:  
 <% = @ course.year% > 
 
 
 
 
  Name:  
 <% = @ course.name% > 
  <strong>Commenter:</strong>
  <%= comment.commenter %>
  <strong>Comment:</strong>
  <%= comment.comment %>
 < end > 
 < else > 
 < H2 > No ratings available < / H2 > 
 < end > 
 < / div > 
 < div id= "footer" > 
 <% = link_to "New Comment", new_course_comment_path (@ course) > 
 <% = link_to "Back to course listing", courses_path% > 
 < / div >
