-### Hamming distance between two numbers
+### Hamming distance
 
 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) => 
+const hammingDistance = (num1, num2) =>
   ((num1^num2).toString(2).match(/1/g) || '').length;
-//hammingDistance(2,3) -> 1
+// hammingDistance(2,3) -> 1
 ```
