### Event Loop Execution Example

Source: https://goodjob.guide/anonymous/posts/01963de4-d219-72bf-9d08-b94bf1328280

Demonstrates the order of execution between synchronous code, microtasks (Promises), and macrotasks (setTimeout).

```javascript
new Promise((res) => {
  console.log(1);
  setTimeout(() => {
    console.log(2);
  });
  res();
}).then(() => {
  console.log(3);
});
// Output: 1 -> 3 -> 2
```
