1.1 Introduction

Throughout this course, I teach you how to create a simple Ajax script, which we can use to issue Ajax requests and process different server responses. We then take our simple Ajax script and turn it into a flexible and easy to use Ajax Library. Along the way, we learn how to cope with a few of the issues you may run into while creating your own Ajax Library, such as dealing with GET request caching, providing user feedback and adding older IE compatibility. Finally, we’ll take our complete Ajax Library and use it to build a small, Ajax search form using the Laravel PHP framework.
