The following npm versions of date-fns-scripts are flagged malicious: 9.9.9. Treat any of these as compromised.

How do I remediate date-fns-scripts if I installed it?

I already installed date-fns-scripts — how do I know if it already compromised me?

If date-fns-scripts was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
