Tell us what’s happening:

Your code so far


// Only change code below this line
var array=[];
function countdown(n){
 if(n<1) {return array;}
else  { 


array.push(n);

array=countdown(n-1);

return array;

}


 
}
// Only change code above this line
console.log(countdown(5)); // [5, 4, 3, 2, 1]

Your code contains global variables that are changed each time the function is run. This means that after each test completes, subsequent tests start with the previous value. To fix this, make sure your function doesn’t change any global variables, and declare/assign variables within the function if they need to be changed.

Example:

var myGlobal = [1];
function returnGlobal(arg) {
  myGlobal.push(arg);
  return myGlobal;
} // unreliable - array gets longer each time the function is run

function returnLocal(arg) {
  var myLocal = [1];
  myLocal.push(arg);
  return myLocal;
} // reliable - always returns an array of length 2
