Implement a hook useCountdown(initialValue, interval) that manages a countdown timer.

The hook should:

• Accept an initial number value and an interval in milliseconds.
• Return an object containing:
  • value: current countdown value.
  • start(): function to start the countdown.
  • pause(): function to pause the countdown.
  • reset(): function to reset to the initial value.
• Automatically decrement the value by 1 at each interval until it reaches 0.

Examples

const countdown = useCountdown(10, 1000);
countdown.start();
// countdown.value decreases from 10 to 0 every second
countdown.pause(); // pauses the countdown
countdown.reset(); // resets value to 10
