Review Summary

Your solution is approved because it correctly implements the required gallery behavior: clicking a thumbnail image or its surrounding link updates the main large image using event delegation on the gallery list. The handler in src/scripts/main.js properly distinguishes between IMG and A targets and sets largeImg.src accordingly, so all core functional requirements for the task are met.

There are a couple of small robustness improvements you can make next time you revisit this code: on the line where you currently call e.preventDefault() unconditionally in the click handler, consider moving that call inside the branches that handle IMG and A so other click types keep their default behavior. Similarly, in the IMG branch, you do e.target.closest('a').href; it would be safer to store const anchor = e.target.closest('a') and check that anchor is not null before reading anchor.href, in case the markup changes and an image is no longer wrapped in a link. As a low-priority accessibility enhancement, you could also update largeImg.alt based on the clicked thumbnail’s alt so screen readers get the correct description when the main image changes.

Overall, this is a clear, focused implementation that meets the task goals, and the remaining suggestions are minor improvements you can treat as learning opportunities for future projects.

Calling e.preventDefault() unconditionally prevents the default action for all clicks inside the list (including non-anchor clicks). Consider moving preventDefault() into the branches that handle anchor clicks (or only call it when the click target or its closest ancestor is an a) so other clicks don't get their default behavior blocked.

When handling the IMG case you call e.target.closest('a').href without checking that closest('a') actually found an anchor. Add a null-check (or guard) before accessing .href to avoid potential runtime errors if the markup changes.
