 ### Hexcode to RGB
 
-Use `Array.slice()`, `Array.map()` and `match()` to convert a hexadecimal colorcode (prefixed with `#`) to a string with the RGB values.
+Use bitwise right-shift operator and mask bits with `&` (and) operator to convert a hexadecimal color code (prefixed with `#`) to a string with the RGB values.
 
 ```js
-const hexToRgb = hex => `rgb(${hex.slice(1).match(/.{2}/g).map(x => parseInt(x, 16)).join()})`
+const hexToRgb = hex => {
+  const h = parseInt(hex.slice(1), 16);
+  return `rgb(${h >> 16}, ${(h & 0x00ff00) >> 8}, ${h & 0x0000ff})`;
+}
 // hexToRgb('#27ae60') -> 'rgb(39, 174, 96)'
 ```
