Summary

Although a lot of this book discusses the bigger picture of designing an application, there are many different criteria for developing a successful product. Attention must be paid to the smaller things that we've already mentioned (such as semicolon style or naming conventions) in order to not only provide a solid foundation for your code, but also to ensure everyone who is working with it feels invested and on the same page. You're not only painting a picture of a well-architected application, but you're also building an intricate machine with hundreds of moving parts. All of them need to be well oiled for your project to succeed.

In the next chapter, we'll start to talk about the theory of application structure and discuss design patterns that will help shape our code base. We'll frame this in the context of Ext JS and show how it provides a strong set of features that build on these patterns and enable us to begin setting up the architecture for a robust application.
