But the console.log(num). I canβt change that.

It looks like you are supposed to make a function.
Which you already have the code for (but with a `}` in the wrong spot).
Revised:

``````function isPrime(n) {
if (n < 2) {
return false;
}
for (let i = 2; i <= Math.sqrt(n); i++) {
if (n % i === 0) {
return false;
}
}
return true; // is outside the for loop
}
``````

And then you could do a loop (where the function is called inside of it) to find the largest prime β€ `n`.
