Code looks good.
I just have some suggestions.

Could consider wrapping all the code and variables needed to support auto-play inside a function as:
function setupAutoPlay() {
// JavaScript support closure. So even after this function call returns, the
// inner function can still access these variables.
let autoPlayInterval = null;
const toggle = document.getElementById("auto-play-toggle");
const statusText = document.getElementById("auto-status");
toggle.addEventListener("change", () => {
...
});
}and then call the function in the onload event listener as
window.addEventListener("load", () => {
button.addEventListener("click", displayRandomQuote);
// By placing the setup code in a separate function, it makes finding out "what operations are
// performed once on page load" easier.
setupAutoPlay();
displayRandomQuote();
});| const quoteEl = document.getElementById("quote"); | ||
| const authorEl = document.getElementById("author"); | ||
| const button = document.getElementById("new-quote"); | ||
|
|
||
| // Generate a random quote using Math.random (required for tests) | ||
| function getRandomQuote() { | ||
| const index = Math.floor(Math.random() * quotes.length); | ||
| return quotes[index]; | ||
| } | ||
|
|
||
| // Put the quote + author into the DOM | ||
| function displayRandomQuote() { | ||
| const q = getRandomQuote(); | ||
| quoteEl.textContent = q.quote; | ||
| authorEl.textContent = q.author; | ||
| } |

Could consider declaring top-level variables and defining functions outside of the onload event listener. Doing so could make finding out "what operations are performed once on page load" easier.
