JavaScript Event Loop: The Truth About setTimeout(0)

The Real Order of Operations:

1. Call Stack: Synchronous code (A, D) - This is where JavaScript executes code sequentially, like reading a noscript.

2. Microtasks: Promises (C) - These are small tasks that need to be executed ASAP after the current noscript, before the next rendering. Think of them as urgent side tasks.

3. Macrotasks: Timeouts/Intervals (B) - These are longer tasks that the browser queues up to do whenever it gets a chance. They're not as urgent as microtasks.

Golden Rule: "0ms" doesn't mean immediate - it means "next event loop tick".
