Determines whether a given JavaScript value is a JS WeakSet. Useful for type checking WeakSet instances, including cases across realms or iframes, and it accounts for ES6 @@toStringTag.
Project status
- The repo appears to be in ongoing maintenance rather than abandoned, with an upstream push on 2026-01-13 (recent activity), though the most recent provided published updates are older (v2.0.4 in 2024-12-17).
- Update cadence looks infrequent and irregular: published updates were released in 2019, 2021, 2024 (v2.0.2 in 2021, v2.0.3 in 2024, v2.0.4 in 2024), with a long historical gap between earlier versions and the jump to v2.x.
