I’ve noticed that the “Run the Tests” button is not working anymore for me. Usually down the bottom it tells me which aspects have passed or failed. From “ES6: Set Default Parameters for Your Functions” onwards it’s not working (link below). Pages before that work fine. I have tried different browers, computers and networks to no avail.
Stratch that. It’s working now. I entered the code wrong. Strange that it didn’t run the test at all though and tell me which tests failed.
