Final challenge objective

Have been sitting on this code for a while but can't think of a way to print code 12 times to get even numbers. Feel like im smashing my head against a wall. Any help would be fantastic!

script.js
for (var i = 0; i < 24; i+=2) {
  console.log (i);
}

Have you tied running your code in the console? I would think once you see your actual results you would notice the two items that need to be changed to get the desired results.

The challenge looks like it wants you to start from 2 instead of 0. Also, your conditional should be inclusive when checking whether or not i is less than or equal to 24. So your loop should look more like this:

for (var i = 2; i <= 24; i+=2)

EDIT: I tested this in the Google Chrome console. Accessed by pressing F12 and clicking the "console" tab.
