function countdownTimer(minutes) {
  let seconds = minutes * 60;
  const countdown = setInterval(function () {
    seconds--;
    if (seconds < 0) {
      clearInterval(countdown);
    } else {
      console.log(seconds + " seconds left");
    }
  }, 1000);
}
```


Create a countdown timer


```javascript
function findSecondLargest(arr) { 
  arr.sort((a, b) => b – a); 
  return arr[1]; 
}   
```

```javascript
function fibonacciSequence(numTerms) { 
  if (numTerms <= 0) return []; 
  if (numTerms === 1) return [0];
  let sequence = [0, 1];
  while (sequence.length < numTerms) { 
    let nextNumber = sequence[sequence.length – 1] + sequence[sequence.length – 2]; 
    sequence.push(nextNumber); 
  }
  return sequence;
}
