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 script. 2. Microtasks: Promises (C) - These are small tasks that need to be executed ASAP after the current script, 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".
