Why this array is being arranged from the last?

JavaScript

Tell us what’s happening:
In this exercise example,

function countup(n) {
  if (n < 1) {
    return [];
  } else {
    const countArray = countup(n - 1);
    countArray.push(n);
    return countArray;
  }
}
console.log(countup(5)); // [ 1, 2, 3, 4, 5 ]

The numbers are in ascending order.
The solution is however is in descending order. the unshift(n) happens only after the recursive function has called itself upto 4 to 1, and then we add 5 in the beginning. That makes sense. The example didn’t make sense to me how the numbers were arranged from small to large?

Your code so far

function countdown(n){
  if (n < 1) {
    return [];
  } else {
    var myCount = countdown(n - 1);
    myCount.unshift(n);
    return myCount;
  }
}
```js

Try this code visualizer and see if you can make sense of it by looking at the code as it is executed.

Both my code and the example code arranged the numbers in ascending order in the visualizer.

The visualizer is cool by the way.
