Usage

const hammingDistance = require('hamming');

console.log(hammingDistance('foo', 'foo')); // 0
console.log(hammingDistance('for', 'foo')); // 1
console.log(hammingDistance('foobar', 'fudbaz')); // 3
console.log(hammingDistance('unequal', 'length')); // null

Hamming distance requires both strings to have the same length.
