Hi everyone,

I’m trying to deeply understand how Node.js works under the hood, beyond just using APIs.

Specifically, I want to understand:

• The internal architecture (event loop, libuv, V8, etc.)
• How asynchronous operations are handled
• How the call stack, callback queue, and event loop interact

Also, is there any tool or platform where I can:

• See Node.js code execution step-by-step
• Visualize how the event loop processes tasks
• Debug or trace execution at a lower level

I’m not looking for beginner-level explanations — I want something closer to how it actually works internally.

Any resources, tools, or explanations would be really helpful.

Thanks!
