Overview

A byte buffer that crosses the JS boundary as a Uint8Array (rather than a plain Array). Wrap a host method's byte-array result in this so JS sees a real typed array — e.g. TextEncoder#encode, Blob#arrayBuffer. The reverse direction (a JS ArrayBuffer/TypedArray argument) arrives as a Bytes too. It subclasses Array so plain-Array callers (and == [..] comparisons) keep working; only the bridge treats it specially.
