const today = formatDate(new Date(), "YYYY-MM-DD"); // "2026-03-15"0 Dependencies
No external runtime packages. Zero supply-chain risk and zero transitive dependency bloat.
Subpath Imports
Direct entry points for each module. Your bundler only ships the code your app actually calls.
Strict Types
Written natively in strict TypeScript. Built-in declaration maps with precise generics.
