In this chapter, we have seen how much of the browser environment has changed over the past 5 years. With new APIs that have enhanced the way we code, through to the DOM APIs that have allowed us to write rich UIs with built-in controls, we are now able to become as vanilla as possible with our applications. This includes the use of fetching external data, along with the new asynchronous APIs such as promises and the async/await system.

In the next chapter, we will be looking at a library that focuses on outputting vanilla JavaScript and giving us a no runtime application environment. We will also be incorporating most of the modern APIs into the rest of the book when we talk about nodes and workers. Play around with these systems and get comfortable with them because we are just getting started.
