-When loading the page, it displays the number of likes for XYZ page.
-When clicking the like button, it likes XYZ page for that person. (May require login if not logged into Facebook.)
-After the person clicks the like button, the number of likes displays the new number of likes at that time without refreshing i.e. async.
After the website is done, I would get the code.
Simple code and quick is preferred.
XYZ Co. has 2,855 Likes.
