Question

Usually, when challenging, I get to see quizzes that I consider very confusing.
The most confusing of them all to me are quizzes such as this:

function foo(x) {
if(x <= 2) {
return x;
}
else {
return foo(6) + foo(x + 2)
}
}

foo(8);

I can't recall how many times I've seen such quizzes and missed them.
I would appreciate it, if you better coders could throw more light on the quiz above 👆 👆
