🧐 Why This Project?

JavaScript is famous for its quirks (e.g., [] == ![] being true). While these look like memes, they are rooted in the ECMAScript specification. This project aims to:

• Document "WTF" moments in JS.
• Explain the underlying logic behind these edge cases.
• Help developers avoid common pitfalls in production.

🚀 Key Features

• Interactive Spoiler: Guess the output before revealing the answer.
• Multilingual Support: All cases are documented in both English and Korean.
• Data-Driven: Easily extensible via cases.json.

🛠 How to Contribute

We love new "king-bad" (annoying) JS snippets! If you know a weird behavior:

1. Fork this repository.
2. Add your case to cases.json.
3. Open a Pull Request.

Please check CONTRIBUTING.md for detailed guidelines.
