core-util-is provides the `util.is*` functions introduced in Node v0.12. It is useful if you want the same set of Node core `util.is*` helpers in your JavaScript code.
Project status
- Maintenance status: No tagged updates are shown after v1.0.3 (2021-08-31), and given today’s date (2026-08-12) the source appears quiet or in maintenance mode, with only an upstream push on 2025-11-25 indicating occasional activity but not necessarily packaged changes.
- Update cadence: Based on the provided tags, the cadence is very infrequent (2014, 2015, 2021, then none shown in 2022 to 2026), so practical cadence is long gaps between published updates.
