primes between two numbers

function generatePrimes(start, end) {
  // Check if start and end values are valid
  if (start < 2 || end < 2 || start > end) {
    return "Invalid input";
  }

  let primes = [];

  // Loop through all numbers from start to end
  for (let i = start; i <= end; i++) {
    let isPrime = true;

    // Check if the current number i is prime
    for (let j = 2; j <= Math.sqrt(i); j++) {
      if (i % j === 0) {
        isPrime = false;
        break;
      }
    }

    // If the current number is prime, add it to the primes array
    if (isPrime) {
      primes.push(i);
    }
  }

  return primes;
}

// Example usage
console.log(generatePrimes(10, 50)); // Output: [11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47]
