Generate Programming Quiz Questions

Generate Programming Quiz Questions

Generate high-quality, bilingual (English/​Chinese) programming quiz questions that test deep understanding rather than rote memorization.

Quality Standards

Core Philosophy: No Rote Learning, Deep Understanding Only

• AVOID: Pure definition questions (e.g., "What does CPU stand for?")
• PREFER: Principle/​scenario questions (e.g., "Why should CSS animations use transform instead of width?")
• Questions should reveal underlying mechanisms, common pitfalls, or real-world production issues

Question Categories to Cover

• JavaScript quirks and internals (type coercion, event loop, closures, this binding)
• CSS layout and performance (BFC, reflow/​repaint, animation optimization)
• Browser APIs and Web Platform (DOM, Storage, Workers)
• Network and HTTP (caching, CORS, protocols)
• System Architecture (memory, CPU cache, concurrency)
• React/​Vue/​Framework internals
• Performance optimization patterns
• Security (XSS, CSRF, CSP)
• Algorithm fundamentals (from Nowcoder TOP101)

Difficulty Levels

• Easy: Basic concepts with common gotchas
• Medium: Requires understanding of underlying principles
• Hard: Edge cases, performance implications, or cross-cutting concerns

Required Output Format

Generate questions as valid JSON array entries matching this schema:

{
  "id": "category-topic-number",
  "category": {
    "en": "Category Name",
    "cn": "分类名称"
  },
  "difficulty": "Easy|Medium|Hard",
  "question": {
    "en": "Question text in English?",
    "cn": "中文题目描述？"
  },
  "options": {
    "en": ["Option A", "Option B", "Option C", "Option D"],
    "cn": ["选项 A", "选项 B", "选项 C", "选项 D"]
  },
  "answer": 0,
  "explanation": {
    "en": "Detailed explanation with why, production tips, and light humor.",
    "cn": "深入浅出的原理解析，包含原因、生产建议和适当幽默。"
  }
}

Explanation Guidelines

Each explanation should include:

1. WHY: Why the correct answer is correct and why others are wrong
2. PRO-TIP: Real-world best practices or production advice
3. HUMOR: Light touch of humor to make learning enjoyable (optional but encouraged)

Workflow

1. Read the current questions from src/​data/​questions.json to understand existing style and avoid duplicates
2. Generate new questions following the format above
3. Ensure bilingual consistency (术语翻译准确，如 Closure = 闭包)
4. Add the new questions to the JSON file
5. Test with npm run dev and use ?dev=1 to preview

Example High-Quality Question

{
  "id": "js-promise-1",
  "category": { "en": "JavaScript", "cn": "JavaScript" },
  "difficulty": "Hard",
  "question": {
    "en": "What is the output order of: `console.log(1); Promise.resolve().then(() => console.log(2)); console.log(3);`?",
    "cn": "`console.log(1); Promise.resolve().then(() => console.log(2)); console.log(3);` 的输出顺序是？"
  },
  "options": {
    "en": ["1, 2, 3", "1, 3, 2", "2, 1, 3", "3, 2, 1"],
    "cn": ["1, 2, 3", "1, 3, 2", "2, 1, 3", "3, 2, 1"]
  },
  "answer": 1,
  "explanation": {
    "en": "Microtask magic! Synchronous code runs first (1, 3), then the microtask queue is flushed (2). Promise.then() callbacks are microtasks, not macrotasks like setTimeout. Understanding this order is crucial for debugging async code - and for not pulling your hair out during interviews.",
    "cn": "微任务魔法！同步代码先执行（1, 3），然后清空微任务队列（2）。Promise.then() 回调是微任务，不像 setTimeout 那样是宏任务。理解这个顺序对调试异步代码至关重要——也能让你在面试中少掉几根头发。"
