Here's a few hints:

  • you don't need a function for this challenge
  • but if you want to use one, it needs to take an argument (and log it out)
  • you need to log the number (or call your function) from inside the loop

appreciate the guidance I was able to use a for loop to resolve it for( I=2; I<25; I+=2){ console.log(i); }

The "do" loop would have also worked with the same loop body.

Glad I could help. And happy holidays!   :christmas_tree:

Looking at this there are probably a few things you can change to get it to work! First, it looks like you you're calling a function once which will only give you a singular log. You can just log the number within the loop instead of doing that separately! Second, be sure that you have something in the log method i.e console.log(num).

putting the I in the console definitely helped appreciate it
