How can I use JavaScript to generate a random prime number between 100 and 1000? Please provide the code for the calculation.

here is the javascript code to generate a random prime number between 100 and 1000:
```
function isprime(num) {
 if(num < 2) return false;
 for(let i = 2; i <= math.sqrt(num); i++) {
 if(num % i === 0) return false;
 }
 return true;
}
function generaterandomprime() {
 let num;
 do {
 num = math.floor(math.random() * 901) + 100;
 } while(!isprime(num));
 return num;
}
console.log(generaterandomprime());
```
the `isprime` function checks whether a number is prime or not. the `generaterandomprime` function generates a random number between 100 and 1000 using `math.random()` and keeps generating new numbers until it finds a prime number using the `isprime` function. finally, the function returns the generated prime number.

The `isPrime` function checks whether a number is prime or not. The `generateRandomPrime` function generates a random number between 100 and 1000 using `Math.random()` and keeps generating new numbers until it finds a prime number using the `isPrime` function. Finally, the function returns the generated prime number.
