Thank you for your answer, I will check everything:)

Hi, I'm passing all basic tests and 191 random tests, but I have no idea why I'm failing the others. Can anybody give me a clue ?

Thank you !

Hi, I was trying to remove all special characters like "<" or "/" with s.replaceAll() but I'm getting an error message saying that s.replaceAll is not a function. I don't understand why I'm getting this message. Could someone give me a hint to start in the good direction with this ?
Thanks :)

Okay, thanks !

Okay, but I still don't understand why my code is working with this case on codepen and not here. That's why I thought there was an issue.

My first question is quiet incorrect. The exact error is "Wrong output for '123*': expected true to equal false" (where * is a space that was not appearing in my previous question).
