Quiz App (Vanilla JS)

A small, accessible quiz application implemented in plain (vanilla) JavaScript. It is intended as a learning example or a lightweight prototype. The app focuses on being simple, keyboard-friendly, and accessible.

How this project was built

• Learning project
• Initial skeleton generated with GitHub Copilot
• The rest was vibe-driven development with heavy AI assistance
• Every line was reviewed, tested, and either kept with confidence or rewritten/deleted by me
  → The final code contains only what I'm confident in and take responsibility for

Features

• Lightweight client-side implementation
• You can provide a seed to reproduce the same question order using the seed input field.
• Keyboard-first interactions
• Supports Tab, Enter, Space, and arrow keys so the quiz can be fully operated from the keyboard.
• Score and high score
  • The results screen shows the current score.
  • High scores (best correct answers) are saved to localStorage using the key quiz_highscore_v1 and displayed on the results screen.
• Responsive, modern UI
  • Simple card-based UI with responsive layout for mobile and desktop.
