Now that we have a good understanding of how the pieces of WebRTC are used, we are going to build our first WebRTC-enabled application. By the end of this chapter, you will have a working WebRTC web page where you can see the technology in action. We are going to pull all the information we just covered in to an easy-to-develop example. We will cover:
Creating a RTCPeerConnection
Creating the SDP
offerand responseFinding ICE candidates for peers
Creating a successful WebRTC connection
