Tell us what’s happening: I am trying to understand the process/ logic of this exercise. it asks that if (n<1) it should return an empty array, if (n===5) then the array shoud return [5,4,3,2,1] & if (n===10) then the array shoud return [10,9,8…1] just not sure enough how to put it into code. a…

The code you have now is implementing a counting up, not counting down, which is why the tests are not passing. You have to inform the function to begin at the number it was given and then count down from there. This can be done in a few ways: using concat or the spread operator are two. Here is on…

Thanks :+1: Im struggling to get my head arround the logic, you say I am using a countup, how is this? Thats why I am not understanding how the logic quite works yet.

I cant rememeber seeing the (…countdown) or similar in the tutorials.

how are you with understanding recursion? maybe take a look at this post: [image] freeCodeCamp Challenge Guide: Use Recursion to Create a Countdown Guide Guide to understanding recursion As it’s one of the most frequently asked questions on the forum I’ve decided to answe…

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge. We are trying to cut back on the numbe…

The intent in this exercise is for you to take the countup example code and modify it to instead countdown. Countup uses push, but you can change that to a countdown by changing the push to a [???].

well I used .pop, but i am stuck with: countdown(10) should return [10, 9, 8, 7, 6, 5, 4, 3, 2, 1] countdown(5) should return [5, 4, 3, 2, 1] using the same formula as in the example.

looking things up, maybe I need to use unshift.

the answer was unshift, looking at examples in w3schools, unshift adds element to the array. :smiley: :smiley: :+1: :+1: :clap: :clap: :clap:

There you go. Push adds to one side of the array and unshift adds to the other.
