Confused about how `process.nextTick()`, `setTimeout(0)`, and `setImmediate()` actually work in Node.js? 🤔

In this short, we break down how the *event loop phases* determine the execution order:
✅ `process.nextTick()` → runs immediately after the current operation, before the event loop continues.
✅ `setTimeout(0)` → runs in the **timers phase**, not truly instant.
✅ `setImmediate()` → runs in the **check phase**, after I/O callbacks.

💡 Priority order: *nextTick → setTimeout(0) → setImmediate()*

Mastering this helps you avoid async bugs and write cleaner Node.js code!
