Calculate the xor distance between two buffers as a new buffer and compare computed distances with eachother

npm install xor-distance

Usage

var distance = require('./')

var dist1 = distance(new Buffer('foo'), new Buffer('bar'))
var dist2 = distance(new Buffer('foo'), new Buffer('baz'))

// the following returns true since the distance between foo and bar
// is greater than the distance between foo and baz
console.log(distance.gt(dist1, dist2))
