More FAQs in Bonus Machine Coding Questions to Practice
Star rating, todo list with filters, nested comments (Reddit-style), tic-tac-toe, stopwatch, calculator, password strength meter, drag and drop list, tooltip component, and BFS visualizer. Practice these after mastering the common questions.
Use a tree data structure. Write a recursive render function. Each comment has reply, vote, and collapse handlers. Indent nested comments. Handle reply (add a child), vote (update score), and collapse (toggle children visibility).
Use the HTML Drag and Drop API: dragstart (store the dragged item), dragover (prevent default to allow drop), drop (reorder the list). Update the data array and re-render. Add visual feedback (highlight the drop target).
