Did you ask that question to test out knowledge?

Well wrong place, ask such "test" questions on feed post. Self Answering is considered as offense. I would suggest you to remove the thread from here.

Answer 3

Output :

1
NaN
NaN

Because you are using console.log inside the function and the function itself is a recursive function :))

I think you supposed to write this :

function a(x){
if(x > 0){
return x * a(x - 1);
}else{
return 1;
}
}

console.log(a(3)); // 6

Thank you Are Rahim Badsa

Answer 5

Rick Grimes Thank you. I never knew that such is offensive. It actually came out in the path of self discovery that I often fail not because I don't know but as a result of not being careful to read through questions.
Thank you for the guidance.
