extendHex
Extends a 3-digit color code to a 6-digit color code.
Use Array.map(), String.split() and Array.join() to join the mapped array for converting a 3-digit RGB notated hexadecimal color-code to the 6-digit form.
Array.slice() is used to remove # from string start since it's added once.
const extendHex = shortHex =>
'#' +
shortHex
.slice(shortHex.startsWith('#') ? 1 : 0)
.split('')
.map(x => x + x)
.join('');
extendHex('#03f'); // '#0033ff'
extendHex('05a'); // '#0055aa'
