Tell us what’s happening:
'countdown(-1)did not return an empty array.
countdown(10) did return
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
countdown(5) did not return
[5, 4, 3, 2, 1]`
Your code so far
function countdown(n) {
if (n < 1) {
return ;
} else {
const arr = countdown(n - 1);
arr.unshift(n);
return arr;
}
}
return myArray;
}
console.log(countdown(-1));
// Only change code below this line
function countdown(n) {
if (n < 1) {
return [];
} else {
const arr = countdown(n - 1);
arr.unshift(n);
return arr;
}
}
return myArray;
}
console.log(countdown(-1));
// Only change code above this line
