5 * @name bnToU8a
6 * @summary Creates a Uint8Array object from a BN.
7 * @description
8 * `null`/`undefined`/`NaN` inputs returns an empty `Uint8Array` result. `BN` input values return the actual bytes value converted to a `Uint8Array`. Optionally convert using little-endian format if `isLE` is set.

12 * ```javascript
13 * import { bnToU8a } from '@polkadot/util';
14 *
15 * bnToU8a(new BN(0x1234)); // => [0x12, 0x34]
