// Objective: Practice with `setTimeout` and `setInterval` for timing operations.

// 1. Use `setTimeout` to log a message after 2 seconds.

setTimeout(() => {

console.log("This message appears after 2 seconds.");

}, 2000);

// 2. Use `setInterval` to log a message every 3 seconds.

const intervalId = setInterval(() => {

console.log("This message appears every 3 seconds.");

}, 3000);

// 3. Use `setTimeout` to cancel the interval after 10 seconds.

setTimeout(() => {

clearInterval(intervalId);

console.log("Interval cleared.");

},10000);

// Exercise: Experiment with varying the delays and intervals. Try creating a simple timer that counts down every second until it reaches zero, then clears the interval and logs a final message.
