+### Hamming distance between two numbers
+
+Use XOR operator (`^`) to find the bit difference between the two numbers, convert to binary string using `toString(2)`.
+Count and return the number of `1`s in the string, using `match(/1/g)`.
+```js
+const hammingDistance = (num1, num2) => 
+  ((num1^num2).toString(2).match(/1/g) || '').length;
+//hammingDistance(2,3) -> 1
+```
