Does this skill support date-fns version 4?

Yes, it includes modern patterns for v4 features including @date-fns/tz and the TZDate class for robust timezone management.

How does this skill help with application bundle size?

It enforces specific import patterns that allow modern bundlers to tree-shake unused functions, ensuring only the code you actually use is included in your production build.

Can I use this for internationalization (i18n)?

Absolutely. The skill provides patterns for locale-aware formatting using date-fns locales, allowing you to display dates in formats familiar to users worldwide.

Why should I use parseISO instead of the native Date constructor?

Native Date(string) parsing is inconsistent across different browsers and locales. parseISO ensures reliable, standardized ISO 8601 handling regardless of the environment.
