Misterious `RangeError: Invalid count value: -1` error about freecodecamp HOT 6 OPEN

Error is coming from the padRow function, specifically one of the string repeats. Depending on the rowCount and rowNumber, when rowCount - rowNumber or 2 * rowNumber - 1 will be -1, calling repeat method of string will show that error.

" ".repeat(-1) // RangeError: Invalid count value: -1

Edit:
When while condition is done < count there's no such issue.

Yep. I think reworking the lessons so we never leave the learner with broken code (or at least never unexplained broken code) is the way to go.

I'm not sure if it was even intended to have broken code, description is suggesting everything should work fine. Step 91 asks for two changes, one of which specifically makes this error appear (second change fixes the issue). 🤷‍♂️

Yeah, it's a bit confusing. Probably not intentional, though. On 91 there's this:

When you do this, you may see a Range Error, because we've created another off-by-one error.

...but the only time I don't see the error is when I've followed all the instructions on step 91.
