Mathias Bynens 8ee50178f3 Avoid confusing prototype methods for static methods
Correct: `Array.from()` (it’s a static method)
Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method)

This patch uses the common `#` syntax to denote `.prototype.`.

### arrayToHtmlList
Converts the given array elements into `<li>` tags and appends them to the list of the given id.
Use `Array.prototype.map()`, `document.querySelector()`, and an anonymous inner closure to create a list of html tags.
```js
const arrayToHtmlList = (arr, listID) =>
(el => (
(el = document.querySelector('#' + listID)),
(el.innerHTML += arr.map(item => `<li>${item}</li>`).join(''))
))();
```
```js
arrayToHtmlList(['item 1', 'item 2'], 'myListID');
```
