Congratulations on making it this far. If you have successfully completed this chapter, you are well on your way to making larger WebRTC applications. The goal of the this chapter was not only to create a WebRTC application but also to understand what happens at each step of the process.

After this chapter, it should already be clear that WebRTC is a complex piece of technology. We covered a great deal of information on the inner workings of WebRTC. Although it is not required to know every bit about how WebRTC is implemented in browsers today, having an understanding of how the major parts work together will help you understand the examples to come.

In this chapter, we covered the inner workings of how peer connections are created in the browser. We covered several of the technologies that enable this, including UDP, SDP, and ICE. You should now have a surface-level understanding of how two browsers can find each other and communicate over the Internet.

It would be a good idea to review...
