ObliviousSet

ObliviousSet provides a JavaScript Set-like data structure where each entry is associated with a Time-To-Live (TTL). Unlike traditional caching mechanisms that often rely on intervals or timeouts for eviction, ObliviousSet's design avoids these, enabling proper garbage collection of the set instance when no active references exist. The current stable version is 2.0.0, which targets modern Node.js environments (>=16). While a strict release cadence isn't published, the package is actively maintained with updates released as needed for features or bug fixes. Its key differentiator is the efficient, passive expiration model where entries are only 'removed' (marked as expired) when explicitly checked via the `has()` method or when iterating over active elements, rather than through eager background processes. This minimizes overhead and resource consumption.
