New Nodejs Event Loop Workshop

[vagostep]

Hi all, I'd like to propose a new Workshopper about Node.js Event Loop.

There is a tool I've been working on it, a Nodejs Event Loop Visualizer. With this tool, we can explain a lot of topics like the phases, and show them with real examples about how the Nodejs Event Loop handles different kind of sync & async codes. Like http servers, streams, timers, and so on. This is an open source tool and everyone can try it.

I can either collaborate or create it. I strongly believe this tool will bring a lot of visibility when it comes to talk about the Event Loop

This looks fantastic! The Node.js Event Loop is one of the hardest things to teach effectively, and your visualizer makes it much more approachable.

I really like how it demonstrates the phases in real time. I can see this being super helpful in a workshop setting — especially for newcomers who struggle to understand where callbacks go, how timers work, and what happens between ticks.

I'd love to see this turned into a Workshopper. Maybe each step could focus on different async patterns (e.g., timers, streams, promises, setImmediate vs process.nextTick).

Count me in to help test or contribute if this moves forward!
