Realm Database for JavaScript

Realm JS is an offline-first, mobile-optimized database designed for JavaScript environments including React Native, Node.js, and Electron. It provides direct access to data as native JavaScript objects, eliminating the need for ORMs and offering performance often surpassing raw SQLite operations. The current stable major version is v20.x, with v20.2.0 being a recent release. Realm maintains a frequent release cadence, often with minor updates and bug fixes. A key differentiator was its integration with MongoDB Atlas Device Sync, but this feature was officially deprecated and removed starting with v20.0.0. Developers now using `realm` (v20+) should treat it as a robust local-only database, with a separate `community` package available for the sync-less version.
