This is a well-known browser security technique. In JavaScript, calling .toString() on a native browser function returns "function appendBuffer() { [native code] }". Calling it on a JavaScript function returns the actual source code. So if your appendBuffer has been monkey-patched, .toString() will betray you; it’ll return the attacker’s JavaScript source instead of the expected native code string.
The API deals exclusively with bytes (Uint8Array). Strings are UTF-8 encoded automatically. There's no "value stream" vs "byte stream" dichotomy. If you want to stream arbitrary JavaScript values, use async iterables directly. While the API uses Uint8Array, it treats chunks as opaque. There is no partial consumption, no BYOB patterns, no byte-level operations within the streaming machinery itself. Chunks go in, chunks come out, unchanged unless a transform explicitly modifies them.。关于这个话题，同城约会提供了深入分析
