Error in Scoreboard.js PropTypes: "'types' can only be used in a .ts file"

npm start throws an error message. I tried just downloading the code and using that, but the issue persists. The entire static propTypes declaration is underlined in red. Anyone else have the same issue?

The Error you're getting is because you kept the semi colon in the code and that doesn't follow the guidelines set by ESlint changing it to an equals sign will fix this error you're getting. whatever you use doesn't break the application but if you want to have the error disappear you're gonna need the equals sign.

Hope this helps!

Maybe the video should be updated because I saw this question elsewhere regarding the same issue. This is very frustrating.

@kzinser It is frustrating, but don't let that deter you. Finding those nuances in the languages is always gonna happen. Keep at it! But yes, the video should be updated. 🙈
