A simple Express API to check if a number is prime.

const isPrime = (num) => {
    if (num < 2) return false;
    for (let i = 2; i <= Math.sqrt(num); i++) {
        if (num % i === 0) return false;
    }
    return true;
};
exports.checkPrimeNumber = async (number) => {
    try {
        return {
            status: 1,
            message: number + (isPrime(number) ? " is a Prime Number" : " is NOT a Prime Number"),
            result: isPrime(number)
        };
    } catch (error) {
        return { status: 500, message: "Internal Server Error",error};
