import { initCppJs } from './native/Factorial.h';

const { Factorial } = await initCppJs();
const factorial = new Factorial(99999);
const result = factorial.calculate();
console.log(result);

src/native/Factorial.h

class Factorial {
private:
    int number;

public:
    Factorial(int num) : number(num) {}

    int calculate() {
        if (number < 0) return -1;

        int result = 1;
        for (int i = 2; i <= number; i++) {
            result *= i;
        }
        return result;
    }
};
