Code editor issue

Question

I wrote a piece of code, but the Solo editor has a problem with the JavaScript code part.
While I ran it in CodePen without any problem.
Where is the problem?

I checked, there is no problem in the solo web version and the code works correctly. But because I can't check with my phone, I don't know if it works properly on phone or not .

You actually removed a code and the error was fixed, but you crashed the program.
