Chapter 5. AJAX Chat

We are living in a world where communication has become very important; there’s a real need to be able to communicate quickly and easily with others. Email, phone texting, postal letters, and online chat offer media through which people can exchange ideas in the form of written words. An important aspect when communicating is the responsiveness factor. While emails and letters don’t offer a live feedback from the other participants, phone and online chat offer a more dynamic way to communicate. In this chapter, we will build an AJAX-enabled online chat solution.
