# CLValue.newCLByteArray

Creates a CLValue of type `ByteArray` from a `Uint8Array`.

## Import

```ts
import { CLValue } from 'casper-js-sdk';
```

## Usage

```ts
const bytes = new Uint8Array(32); // 32-byte hash
const value = CLValue.newCLByteArray(bytes);
```

## Parameters

### val

- **Type:** `Uint8Array`

Raw bytes. The length is encoded as part of the type: `CLType.ByteArray(n)`.

## Return Value

`CLValue` with `clType = CLType.ByteArray(val.length)`.

## Notes

- Use for contract arguments that expect fixed-length byte arrays (e.g., 32-byte hashes).
- Use `CLValue.newCLAny(bytes)` for opaque raw bytes without a fixed length type.
