In this video, I talk about how the Node.js supports concurrency. We take a deep dive in understanding the NodeJS Reactor Pattern and the Event Loop.

During the video, we will understand the consequences of JavaScript’s single-threaded nature and what happens when it has to deal with slow and blocking I/O.

Next, we understand how Non-Blocking I/O works using busy-wait followed by the event demultiplexer approach to handle I/O operations.

Finally, we understand the step-by-step approach of the Reactor Pattern to implement the Node.js Event Loop and the role of libuv in the overall big picture.
