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.
const arrayToHtmlList = (arr, listID) =>
(el => (
(el = document.querySelector('#' + listID)),
(el.innerHTML += arr.map(item => `<li>${item}</li>`).join(''))
))();
arrayToHtmlList(['item 1', 'item 2'], 'myListID');
