+Use `Array.map()`, `split()` and `Array.join()` to join the mapped array for converting a three-digit RGB notated hexadecimal color-code to the six-digit form.
+`Array.slice()` is used to remove `#` from string start since it's added once.
 ```js
 const convertHex = shortHex =>
   '#' + shortHex.slice(shortHex.startsWith('#') ? 1 : 0).split().map(x => x+x).join()
