Day 1: Functions

    Using for loop:

    const factorial = (n) => {
    let fact = 1;
    for( let i = n; i>0; i--){
        fact = fact*i
    }
    return fact;
}

    Using recursion:

    const factorial = (n) => {
    if (n == 1) return 1;
    return n * factorial(n-1);
}

    OR

    const factorial = (n) => n == 1 ? 1 : n * factorial(n-1);
