Description: Optimizing files for Ajax is essential for building an Ajax based application. Every developer wants to their online application to be accessible to as many users as possible. By building a lightweight application, they ensure that any user – whether they are running with the highest bandwidth possible or just through dial up, could easily access their Ajax based website. Although websites could still run and be light without the file optimization, the interactivity and the aesthetic beauty of the website is just not there since so many things are sacrificed just to build an interactive and fully functional website. But with optimization, sacrificing user interaction for the sake of access will never happen.
