Recursion to Create a Countdown problem

Tell us what’s happening:
I’m passing all the tests except for “You should use recursion to solve this problem.”

Your code so far


//Only change code below this line
function countdown(n){
return n > 0 ? [n].concat(countdown(n - 1)) : [];
}
console.log(countdown(5)); // [5, 4, 3, 2, 1]

Challenge: Use Recursion to Create a Countdown

I don’t think the exercise recognizes the recursion being called from the ternary operator. You might try using an actual if, then and see if it fixes the issue.

The issue was actually a bug in the test. It was expecting to see a semi-colon immediately after the function call. I have submitted a pull request to correct the test.
