A note on the output of this loop.

const main = document.querySelector('main'); let html = '';

for (let i = 1; i <= 10; i++) { html += '<div>${i}</div>'; }

main.innerHTML = html;

I found the ${i} selector ended up evaluating to printing '${i}' many times rather than a sequence of numbers.

Instead I wrote the following and it evaluated to the desired result. I am unsure of why the former syntax didn't work.

const main = document.querySelector('main'); let html = '';

for (let i = 5; i <= 100; i+=5) { html += '<div>' + i + '</div>'; }

main.innerHTML = html;

Were you using quotation marks or back ticks?, they do look very similar, but the key for back ticks is usually found on the left hand side of the keyboard, at least on my computers they are (Mac to the left of Z and pc to the left of 1). Template literals require back ticks to be used in order to work, so ${i}.

Those are single quotes in his code so you are correct.
