Tell us what’s happening:
I used github instead of codepen to submit, but the tests came back all failed. Currently my code does what it asks and am unsure if I should just switch back to using codepen.
You must submit a working app, so it can be tested. Most users use Glitch for the backend challenges. You can host your project on a domain of your choosing if you want. Heroku is another on which site users hosted projects.
