In this chapter, we have seen what the MVVM pattern is about and how KnockoutJS implements this pattern to provide you with data-binding capabilities. We realized the application was really simple, but we saw many features of KnockoutJS regardless.

We used three different types of observables (observable, observableArray, and computed). We also saw many different binding handlers and utility functions.

Best of all, we learned how to create a full-featured application using View Model and data binding. There are a few binding handlers we haven't seen, like template or component, but we will see them in the next chapter, and there we will create new custom binding handlers too.
