Learn WebSockets

Build real-time applications like chatrooms and multiplayer games with WebSockets!

### Why Learn WebSockets?

WebSockets is a powerful communication protocol that allows for bidirectional and continuous communication between a server and its clients. Whereas basic HTTP connections are used to build static websites, WebSockets power real-time applications such as browser-based chatrooms, live sports trackers, multiplayer video games, and much more!

### Take-Away Skills

You will learn how WebSockets and HTTP work hand-in-hand to establish a persistent connection as well as the many benefits that WebSockets provide compared to HTTP. You will also be able to use the popular `ws` package and the browser-native `WebSocket` API to build a chatroom application and a fast-paced multiplayer game!
