for a single-file practice set that touches every topic from this workshop.

There are no automated tests or solutions here. Use the comments in the file as your checklist. A few success criteria to keep the vague spots concrete:

Keep one library object with name, address, books, members, and eventsById
Include 6–8 books and 4–5 members, with at least two books sharing a tag, one book without checkedOutByMemberId, and one member without email
formatBook({ title, author, publishedYear }) should return "{title} — {author} ({publishedYear})" (em dash between title and author)
Treat “recent books” as publishedYear >= the current calendar year minus 5
memberNamesSorted should be alphabetical ascending
mergeTags(...tagLists) should return unique tags (first-seen order is fine)
findBooksByTags(books, tags) should require all requested tags to match
