Throughout the course of this chapter, we learned about why it is important to have an optimized frontend for our enterprise applications, and how a frontend may affect the use of our application inside the enterprise. We then moved on to understand what kind of issues usually plague the performance of web frontends, and what possible solutions we can take to improve the application frontend. This involves reducing the amount of resources that are loaded by the frontend, allowing the CSS to load in parallel, bundling JavaScript, and so on. We then moved on to understand how caching can prove to be useful considering the use case of an enterprise web application. Once we understood the concept of caching, we then moved into the territory of web storage, which allows us to store a large amount of data in the client browser, allowing easy access to the data without making a request to the server again and again.

Now, we are ready to take a look at how to mature the process of our application development, and to make sure that we deliver an application with the least number of defects as possible. The next chapter of this book takes us through the process of making sure that the application we are building contains the least number of defects through the use of different testing techniques.
