## Note

This package has inherited its version number from the `@typescript-eslint` project.
Meaning that even though this package is `2.x.y`, you shouldn't expect 100% stability between minor version bumps.
i.e. treat it as a `0.x.y` package.

Feel free to use it now, and let us know what utilities you need or send us PRs with utilities you build on top of it.

Once it is stable, it will be renamed to `@typescript-eslint/util` for a `4.0.0` release.
