function isPrime(number) {
    // Check for divisibility from 2 to number - 1
    for (let i = 2; i < number; i++) {
        if (number % i === 0) {
            return false; // Not a prime number
        }
    }
    return number > 1; // Prime if greater than 1
}

// Check if 13 is a prime number
const result = isPrime(13);

// Display the result
console.log('Is Prime:', result); // Output: Is Prime: true
