"Node.js is an event-based platform. This means that everything that happens in Node is the reaction to an event. A transaction passing through Node traverses a cascade of callbacks. Abstracted away from the developer, this is all handled by a library called libuv which provides a mechanism called an event loop. This event loop is maybe the most misunderstood concept of the platform, yet understanding it is vital to really grasp what Node.js is all about. In this talk I will cover the learnings from digging into the event loop to get some actionable performance metrics out of it."
