2.4. Conclusions

The first part of this chapter showed you how to create a basic Ajax application. After performing that section, you should be comfortable about the basics of Display Manipulation (Chapter 5), Web Remoting (Chapter 6), and Dynamic Behavior (Chapter 7. The second part of this chapter introduced a number of the Ajax Patternsthe point is not to understand those patterns in detail, but to get a feel for the sort of thing the patterns do. That is, to see how they build on top of the basic technologies to improve usability, maintainability, and so on. The final part of this chapter suggested several exercisesI recommend you try one or two if you're still coming to grips with Ajax.

It should be clear by now that although Ajax is a great leap forward for the Web, it's no magic bullet. Developers need to tread carefully in order to ensure their Ajax apps are easy to maintain and easy to use. The next chapter summarizes several key principles for Ajax system design and introduces the Ajax Patterns, which offer practical advice on applying those design principles.
