How does the event loop manage non-blocking I/O? Are non-blocking system calls truly running asynchronously, or are they just waiting for events? How does this architecture contribute to performance? Could you explain it conceptually?
How does non-blocking I/O work in Node.js?

Event loop talk starts my brain going like the green numbers in The Matrix, honestly 😅 It’s like it’s acting as this straight-up "magic gatekeeper," and I’m just sitting here like, "Bro, how does this even work?" In reality, since system calls are non-blocking, the event loop is just like, "Cool, you go ahead, I’ll wait for you to finish," and instead of happening simultaneously, it’s more like all the waiting piles up and then it’s like, "Boom, now!" when everything’s done. The performance part is like, "Bro, the CPU gives everyone a chance where no one’s waiting," and that’s basically how I clumsily explain it to beginners 😂
