-_Note:_ If you try to `console.log(arr)` after each operation in some environments (like Chrome DevTools), you may only see the final state of arr. This happens because the console sometimes keeps a live reference to the array instead of logging its state at the exact moment. To see intermediate states properly, store snapshots using console.log([...arr]) or print values immediately after each operation.
