## ⚡ **實際性能優化實現**

### **P1. React Hooks優化**

#### **P1.1 記憶化函數**
```typescript
// 統計計算優化
const vocabularyStats = useMemo(() => {
  if (!sentenceAnalysis) return null

  const userLevel = localStorage.getItem('userEnglishLevel') || 'A2'
  // 計算邏輯...

  return { simpleCount, moderateCount, difficultCount, phraseCount }
}, [sentenceAnalysis])

// 事件處理優化
const handleAnalyzeSentence = useCallback(async () => {
  setIsAnalyzing(true)

  try {
    await new Promise(resolve => setTimeout(resolve, 1000)) // 模擬延遲
    // 設置假資料...
    setShowAnalysisView(true)
  } finally {
    setIsAnalyzing(false)
  }
}, [])

const handleSaveWord = useCallback(async (word: string, analysis: any) => {
  try {
    const cardData = {
      word: word,
      translation: analysis.translation || '',
      definition: analysis.definition || '',
      pronunciation: analysis.pronunciation || `/${word}/`,
      partOfSpeech: analysis.partOfSpeech || 'unknown',
      example: `Example sentence with ${word}.`
    }

    const response = await flashcardsService.createFlashcard(cardData)
    if (response.success) {
      alert(`✅ 已將「${word}」保存到詞卡！`)
    }
  } catch (error) {
    console.error('Save word error:', error)
    throw error
  }
}, [])
```

#### **P1.2 ClickableTextV2性能優化**
```typescript
// 工具函數記憶化
const getCEFRColor = useCallback((level: string) => {
  switch (level) {
    case 'A1': return 'bg-green-100 text-green-700 border-green-200'
    case 'A2': return 'bg-blue-100 text-blue-700 border-blue-200'
    // ...其他等級
    default: return 'bg-gray-100 text-gray-700 border-gray-200'
  }
}, [])

const findWordAnalysis = useCallback((word: string) => {
  const cleanWord = word.toLowerCase().replace(/[.,!?;:]/g, '')
  return analysis?.[cleanWord] || analysis?.[word] || analysis?.[word.toLowerCase()] || null
}, [analysis])

// 文字分割優化
const words = useMemo(() => text.split(/(\s+|[.,!?;:])/g), [text])
```

  console.log('🚀 handleAnalyzeSentence 被調用 (假資料模式)')

  setIsAnalyzing(true)

  try {
    // 模擬API延遲
    await new Promise(resolve => setTimeout(resolve, 1000))

    const testSentence = "She just join the team, so let's cut her some slack until she get used to the workflow."

    // 完整的假資料設置...
    setSentenceAnalysis(mockAnalysis)
    setSentenceMeaning("她剛加入團隊，所以讓我們對她寬容一點，直到她習慣工作流程。")
    setGrammarCorrection({
      hasErrors: true,
      originalText: testSentence,
      correctedText: correctedSentence,
      corrections: [/* 修正詳情 */]
    })
    setShowAnalysisView(true)
  } finally {
    setIsAnalyzing(false)
  }
}
```

#### **API1.2 真實API準備**

// 註解中的真實API調用代碼
const response = await fetch('http://localhost:5000/api/ai/analyze-sentence', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${localStorage.getItem('auth_token')}`

const getLevelIndex = (level: string): number => {
  return CEFR_LEVELS.indexOf(level as typeof CEFR_LEVELS[number])
}

// ClickableTextV2中的實際分類邏輯
const getWordClass = (word: string) => {
  const wordAnalysis = findWordAnalysis(word)
  const baseClass = "cursor-pointer transition-all duration-200 rounded relative mx-0.5 px-1 py-0.5"

  if (wordAnalysis) {
    const isPhrase = getWordProperty(wordAnalysis, 'isPhrase')
    const difficultyLevel = getWordProperty(wordAnalysis, 'difficultyLevel') || 'A1'
    const userLevel = typeof window !== 'undefined' ? localStorage.getItem('userEnglishLevel') || 'A2' : 'A2'

    if (isPhrase) {
      return "" // 慣用語：純黑字
    }

    const userIndex = getLevelIndex(userLevel)
    const wordIndex = getLevelIndex(difficultyLevel)

    if (userIndex > wordIndex) {
      return `${baseClass} bg-gray-50 border border-dashed border-gray-300 hover:bg-gray-100 hover:border-gray-400 text-gray-600 opacity-80`
    } else if (userIndex === wordIndex) {
      return `${baseClass} bg-green-50 border border-green-200 hover:bg-green-100 hover:shadow-lg transform hover:-translate-y-0.5 text-green-700 font-medium`
    } else {
      return `${baseClass} bg-orange-50 border border-orange-200 hover:bg-orange-100 hover:shadow-lg transform hover:-translate-y-0.5 text-orange-700 font-medium`
    }
  } else {
    return "" // 無資料：純黑字
  }
}
```

#### **A1.2 統計計算算法實現**
```typescript
// 實際的統計計算邏輯
Object.entries(sentenceAnalysis).forEach(([, wordData]: [string, any]) => {
  const isPhrase = wordData?.isPhrase || wordData?.IsPhrase
  const difficultyLevel = wordData?.difficultyLevel || 'A1'

  if (isPhrase) {
    phraseCount++
  } else {
    const userIndex = getLevelIndex(userLevel)
    const wordIndex = getLevelIndex(difficultyLevel)

    if (userIndex > wordIndex) {
      simpleCount++
    } else if (userIndex === wordIndex) {
      moderateCount++
