At a very basic core level, a comparison between @deno_land 2.0 and @nodejs could probably be summarised as:

- JS-runtime: Both uses V8
- Asynchronous I/O: Node.js uses #libuv, Deno uses #tokiors
- Native code: Node.js uses C++, Deno uses Rust

So essentially it boils down to libuv vs tokio […]

7 phases of Handling I/O in #nodejs in #libuv

1️⃣Timers: Expired timer and interval callbacks scheduled by setTimeout and setInterval
2️⃣Pending I/O callbacks: Pending Callbacks of any completed/errored I/O operations
3️⃣Idle handlers: libuv internal stuff
