实现示例：

/**
 * 防抖函数 - 基础工具类
 * @description 在指定时间内只执行最后一次调用
 * @param {Function} func - 需要防抖的函数
 * @param {number} delay - 延迟时间（毫秒）
 * @returns {Function} 防抖后的函数
 */
const debounce = <T extends (...args: any[]) => any>(
  func: T,
  delay: number
): ((...args: Parameters<T>) => void) => {
  let timeoutId: NodeJS.Timeout;
  
  return (...args: Parameters<T>): void => {
    clearTimeout(timeoutId);
    timeoutId = setTimeout(() => func.apply(this, args), delay);
  };
};

// 使用示例
const handleSearch = debounce((keyword: string) => {
  console.log('搜索关键词:', keyword);
}, 300);

export { debounce };

2. 🔧 利用IDE代码片段功能

问题场景：频繁输入重复的代码模板

解决方案：配置IDE代码片段，快速生成常用代码

VS Code 代码片段配置

4. 🤖 自动化代码片段生成

问题场景：手动创建代码片段效率低，容易出错

解决方案：使用脚本自动生成常用代码片段

自动生成Vue组件脚本

import path from 'path';

5. 🔍 智能代码片段搜索与推荐
