Invalid regular expression flag s

Every time I run the test it says
“SyntaxError: invalid regular expression flag s”

Is this up to me or some bug?

Your code so far

Link to the challenge:

does it says something else after that? there should be more to the error

No nothing. And even if I enter another exercise it says the same.

When I run your code, it passes all tests. Is your browser updated to the latest version? Do you have any browser extensions running?

I have the same problem!! i got stuck by it.
(and it’s my third time that showed me the same error)

could you open the browser console and see what error you see there?

Thx, I just updated firefox and It works instantly

I’m glad to hear it. Happy coding!
