Function bytesLen

bytesLen(hexLike: BytesLike): number
Return the number of bytes occupied by hexLike.
Parameters
- hexLike: BytesLike
  Hex-like value
Returns number
Byte length of hexLike.
Example
```
bytesLen("0x48656c6c6f") // 5
bytesLen(new Uint8Array([1, 2, 3])) // 3
bytesLen(new ArrayBuffer(4)) // 4
bytesLen([1, 2]) // 2
```

- bytesFrom - Convert values to Bytes (Uint8Array)
Note
Prefer direct .length/.byteLength access on Uint8Array/ArrayBuffer when you already have bytes. Use bytesLen() only when you need length without performing additional operations.
