Tell us what’s happening:

I can’t get past the 18th test. I don’t see the problem in the inspector and I have even compared the html results with the example. Please help.

Your code so far

Use the example app to complete a sort and take a screenshot of the completed sort.

Hardcode the same array into your app for testing and take a screenshot of the completed sort.

They should be exactly the same.
