javascript使用参数从内部调用函数表达式本身

Question

Please, someone, tell me how is the result 384 here. According to me: Called function value is greater than 2 so, the result should be 8 * fac(8 - 2) 64-2 ans: 62 I understand something happening with "fac" please explain.

let factoria = function fac(n){
    return n < 2 ? 1 : n * fac(n - 2);
}

console.log(factoria(8));
// result 384

Answer 1

This line n * fac(n - 2) is recursively calling the itself with new value. At first it will be called with 8 * fac(8 - 2) so now fac will be called again with 6, then again with 4 and so on

 let factoria = function fac(n) { console.log(n) return n < 2 ? 1 : n * fac(n - 2); // recursive function } console.log(factoria(8));
