 ### 3-digit hexcode to 6-digit hexcode
 
-Use `Array.map()`, `split()` and `Array.join()` to join the mapped array for converting a three-digit RGB notated hexadecimal colorcode to the six-digit form.

+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[0] == '#' ? ('#' + shortHex.slice(1).split('').map(x => x+x).join('')) :
-    ('#' + shortHex.split('').map(x => x+x).join(''));
+  '#' + shortHex.slice(shortHex.startsWith('#') ? 1 : 0).split().map(x => x+x).join()
 // convertHex('#03f') -> '#0033ff'
 // convertHex('05a') -> '#0055aa'
 ```
