The header rule takes the current year as the end of the range, as upstream's does; 581 sources still ended at 2025, which failed lint. Lint never ran to completion here, so this went unseen. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

/**
|
|
* @name u8aToU8a
|
|
* @summary Creates a Uint8Array value from a Uint8Array, Buffer, string or hex input.
|
|
* @description
|
|
* `null` or `undefined` inputs returns a `[]` result, Uint8Array values returns the value, hex strings returns a Uint8Array representation.
|
|
* If `strict` is true, `null` or `undefined` will throw an error instead of returning an empty array.
|
|
* Supports input types: Uint8Array, Buffer, hex string, string, or number array.
|
|
* @example
|
|
* <BR>
|
|
*
|
|
* ```javascript
|
|
* import { u8aToU8a } from '@pezkuwi/util';
|
|
*
|
|
* u8aToU8a(new Uint8Array([0x12, 0x34]); // => Uint8Array([0x12, 0x34])
|
|
* u8aToU8a(0x1234); // => Uint8Array([0x12, 0x34])
