Great breakdown of how Node.js handles asynchronous code and the event loop! The article clearly explains how synchronous code runs first, and how setTimeout schedules asynchronous callbacks to be executed later. It's fascinating to see how even a setTimeout(0) doesn't execute immediately but waits until the call stack is clear. For local development, tools like ServBay can simplify the setup process, allowing you to focus more on coding and less on environment configuration. Definitely worth checking out if you're looking to streamline your dev workflow.
