+ * @description Hashes ENS label
+ *
+ * - Since ENS labels prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to [normalize ENS labels](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `labelhash`. You can use the built-in [`normalize`](https://viem.sh/docs/ens/utilities/normalize) function for this.
+ *
+ * @example
+ * labelhash('eth')
+ * '0x4f5b812789fc606be1b3b16908db13fc7a9adf7ca72641f84d75b47069d3d7f0'
