Help Me Out here please

I just started the javascript course as a beginner, though I’ve done some reading and took some basic javascript courses before now, so at least I understand some few things.

My issue is, I keep getting Uncaught SyntaxError: Invalid regular expression flags, even when the answers are right.

What does this mean please? Is it normal for it to show or what am I doing wrong.

Even ordinary addition is showing error

it means you need to update your browser

Try updating your browser because people have problems with an outdated browser and clear your cookies and cache data too.

Thanks guys, I’ve updated my browser :grinning:
