I cant make Factorial task

Question

Factorial of number 5 is (5*4*3*2*1) understand?
So, i have my premium task, to make factorial by the function “for” with loops. I cant understand how to make it right because every try is all wrong or some tests are right but not all.

Answer 1

Alex , you are right saying that factorial of 5 is 5*4*3*2*1.

- to calculate it, you need a for loop. i think you are familiar with that.
- so use the for loop combined with a range object that contains all numbers you need (1...5) or (2...5 - as multiplying with 1 does not change anything).
- so you just have to make a variable that holds the current product, and update it in each loop iteration.

that's all.

Answer 6

process.stdin.setEncoding('utf-8');
let inputString = '';
process.stdin.on('data', inputStdin => {
inputString += inputStdin;
});
process.stdin.on('end', _ => {
main(inputString);
});
function main(input) {
var number = parseInt(input, 10)
var factorial = number - 1;

for (idk what to write)

console.log(number * factorial--)
