Had some fun with EventListeners...

Instead of adding classes to the list items in the HTML, I added a click EventListener to each item inside the for loop so that when clicked it would display a prompt: "Well, what color should it be?", accepts and input, then turns that list item into that color.

Initially, instead of changing to a specific color, I had the click event add the class "NotOrange" which just turned it black, but this was more interesting :)

const myList = document.getElementsByTagName('li');

for (let i = 0; i < myList.length; i += 1) {
  myList[i].style.color = 'purple';
  myList[i].addEventListener('click', () => {
    myList[i].style.color = prompt("Well, what color should it be?");

That's a cute extension on the exercise!

You might be interested to know that another way to do it is to set up a single delegated handler on the list itself, which will then process all of the items in it:

const myUL = document.getElementsByTagName("ul")[0];
myUL.addEventListener("click", e => {
  e.target.style.color = prompt("Well, what color should it be?");

Besides only needing one of them, another delegated handler advantage is that it will also respond to any items added later.

This is a great, concise solution, thank you Steven! Been trying to wrap my head around how to use .target for a while now and this helps me understand it better.
