- `a` {Buffer | TypedArray | DataView}
- `b` {Buffer | TypedArray | DataView}
This function is based on a constant-time algorithm.
Returns true if `a` is equal to `b`, without leaking timing information that
would allow an attacker to guess one of the values. This is suitable for
comparing HMAC digests or secret values like authentication cookies or
