3. Periodically checking for new posts on the posting list page Using one of the timer functions in JavaScript, make the Post List Page dynamically check back with the server to see if there are any new posts using AJAX. In order to avoid sending the full list of posts back each time, you may find it useful to keep track of the IDs of the most recent post and re-post, and use this to ensure that only new posts are provided back. Keep in mind that the process of inserting the new posts into the page may require a non-trivial amount of programming to ensure that all of the required pieces are put in their proper location (e.g., embedded div tags). Ensure that your code supports the insertion of multiple new posts or re-posts in this manner. For this to work properly with the like and dislike feature, you will need to ensure that new events have been dynamically registered on the like and dislike icons for the new posts.
