js: function with if-statement

Question

function p(m) {
if(m==1) {
return m;
} else {
return m*p(m-1);
}
}
console.log(p(4));
// the right output is 24. and i dont understand it.
// 4*(4-1)=12 is my opinion. what am i thinking wrong…? 🤔

Answer 1

It is a recursive function. It is 4*3*2*1.

Answer 2

It's executed as
4 * p(3)
4 * 3 * p(2)
4 * 3 * 2 * p(1)
4 * 3 * 2 * 1
24

Answer 3

thank you!!! 👍
