Unbox a boxed JavaScript primitive value (for example, Boolean, String, Number, BigInt, or Symbol) back into its underlying primitive. Useful when you need to extract the primitive safely across realms or if you want to avoid relying on `instanceof` or mutable properties.
Project status
- The upstream repo shows an actual push on 2025-12-30, which suggests the project is not abandoned, but published update notes are infrequent (no documented update after v1.1.0 in 2024-12-16).
- Apparent update cadence (based on the available versioned updates): v1.1.0 in 2024, then prior updates in 2022, 2021, and 2019, indicating long gaps between numbered updates.

Recent updates
v1.1.0
v1.1.0 adds TypeScript type definitions for unbox-primitive, and refactors the implementation to use the `call-bound` package instead of `call-bind/callBound`. It also updates several dependencies and test fixtures, and changes CI workflows to split Node 10-20 and 20+ test jobs. The publisher release notes field contains no details, so most user-impacting changes are not described there.

v1.0.2 mainly refactors the internal “call a boxed primitive method” logic to use the newer `call-bind` package instead of `function-bind`. It also updates project tooling and CI workflows, and bumps a handful of dependency versions.
