RangeError: 'offset' is out of bounds when comparing empty (length 0) Buffers

[Ateş Göral]

Test case:

const c = require('concordance');

const a = Buffer.from([]);
const b = Buffer.from([]);

console.log(c.compare(a, b));

Output:

Hi @atesgoral. Which Node.js version are you using?

[Ateş Göral]

@novemberborn v6.0.0

Just tested with 6.11.3 and the problem does not exist. So, maybe this is a non-issue. I didn't realize the particular environment I was using was stuck at version 6.0.0 for no valid reason :)

Interesting. It does look like a Node.js issue, yes.
