Your Tasks

In index.js, implement:

1. lateFee(daysLate)

• If the book is returned on time (or early), there’s no charge.
• If it’s a few days late, charge a dollar per day.
• If it’s more than a week late but under a month, charge two dollars per day.
• If it’s over a month late, suspend the member’s borrowing privileges.

2. branchHours(branch)

• Use a ternary: if the branch is Central, it stays open later; otherwise it closes earlier.

3. recommendBookByGenre(genre)

• Use a switch to suggest different sections based on genre (fiction, non-fiction, comics, or any other).
