二进制到可比较

将 TypedArray 或 ArrayBuffer 转换为可以在 Map 中用于比较的字符串，以查看字节是否相同。

// Turns a TypedArray or ArrayBuffer into a string that can be used for comparison
// in a Map to see if the bytes are the same.
//
export default function binaryToComparableString(
  view: $ArrayBufferView,
): string {
  return String.fromCharCode.apply(
    String,
    new Uint8Array(view.buffer, view.byteOffset, view.byteLength),
  );
}
