Sending a message and getting an instant response without even refreshing the page is something we take for granted. But in the past, enabling real-time functionality was a real challenge for developers. Finally, the developers' community found a solution for building truly real-time apps: Web sockets. Before they came along, the “real-time” web existed, but it was difficult to achieve, typically slower, and was delivered by hacking existing web technologies that were not designed for real-time applications. So,  this article is all about building a deeper understanding of how WebSockets operate and what’s actually going on under the hood of applications using WebSockets. HOW WEB SOCKETS WORK?
