Thank you very much!I had to google to understand a little more about truthy and falsy. this kata is good! please create more!! for a person that is new to JS about 3 months ago i like these fundamental ones.

Truthy and falsy values must be supported. See description.

same I did what you did, but it won't accept my solution for some reason...

function towerCombination(n){
//insert your code here
var total = n;
for (i= n; i>2; i--){
total = total * (i-1);

}

return total;
}
