London | 26-ITP-May | Eyob Zeray | Sprint 2 | Book Library

Changelist

Fixed the following bugs in the Book Library debugging exercise:

1. Website loads but doesn't show any books — missing closing parenthesis in the render() for-loop was causing a syntax error that broke the whole script
2. Error in console when adding a book — submit() was pushing to an undefined library variable instead of myLibrary
3. Title used as author name — Book() was being called with title.value passed twice instead of author.value for the author field
4. Delete button broken — variable was declared as delButton but referenced as delBut, and the event listener used "clicks" instead of "click"
5. Wrong read status saved — the Yes/No display logic was inverted
6. Missing author validation — submit() only checked title and pages for empty values; added a check for author so a book can't be added without one, matching the spec

Tested manually in the browser: books display on load, adding a book with all fields works correctly, missing fields trigger the alert, read status toggles correctly, and delete removes the correct book.
