hammingDistance

Calculates the Hamming distance between two values.

Use the XOR operator (^) to find the bit difference between the two numbers, convert to a binary string using toString(2). Count and return the number of 1s in the string, using match(/1/g).

const hammingDistance = (num1, num2) =>
  ((num1 ^ num2).toString(2).match(/1/g) || "").length;

hammingDistance(2, 3); // 1
