This is my research on Web Sockets. I wanted to make a chat application but I noticed that AJAX request is not great for it. The server is not built to automatically send data to client when there is new data. I talked to fellow coders about it and they said the key is Web Sockets. I thought it would be rewarding to research about Web Sockets on General Assembly's Conference Day!

I made a powerpoint to teach my fellow coders at General Assembly about Web Sockets. The link to the presentation is here: https://docs.google.com/presentation/d/1NDeNy7QdpNirilsnmPw_U5Rth-0u_yRCJIfrTOKhOcM/edit?usp=sharing

According to MDN, "Web Sockets is an advanced technology that makes it possible to open an interactive communication session between the user's browser and a server." Each individual connection between the client and server is called a socket. You can set up so that the server can automatically send data to clients when there is new data.

You have to keep sending GET AJAX request to the server to see if there is new information. You can set a timer to send an AJAX request, but that would not be scalable. The design of AJAX request is not suited for real time data dependent application.
