In this chapter, we discussed Ajax techniques and concepts of using the XMLHttpRequest object. We have seen the basic architecture of how the Ajax request is processed and what events and methods it provides. Similarly, we also discussed what jQuery offers and the extensive library it has for performing different types of the HTTP GET and POST requests. In the next chapter, we will discuss the basics of TypeScript, and one of the most popular client-side framework, Angular 2. We will also go through developing a simple application using ASP.NET Core MVC 6 with Angular 2 as a frontend framework and Entity Framework 7 for backend operations.
