For consistency and a minor performance improvement, consider creating a single Date object at the start of the sitemap function (e.g., const now = new Date();) and reusing it for all lastModified properties. This ensures all URLs generated in this run have the same timestamp and avoids creating unnecessary Date objects inside loops.

changeFrequency: "weekly",
priority: 0.8,
changeFrequency: "daily",
priority: 0.9,
});
}
