### 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.
|
|
|
|
```js
|
|
const extendHex = shortHex =>
|
|
'#' +
|
|
shortHex
|
|
.slice(shortHex.startsWith('#') ? 1 : 0)
|
|
.split('')
|
|
.map(x => x + x)
|
|
.join('');
|
|
```
|
|
|
|
```js
|
|
extendHex('#03f'); // '#0033ff'
|
|
extendHex('05a'); // '#0055aa'
|
|
```
