JavaScript的灵活性是一把双刃剑。分析代码以防止运行时意外。
核心原则: JavaScript的灵活性是一把双刃剑。分析代码以防止运行时意外。
始终:
触发短语:
问题:
异步操作处理不当
错误示例:
- 回调地狱
- Promise未正确处理
- async/await滥用
- 错误处理缺失
解决方案:
1. 使用async/await替代回调
2. 正确处理Promise错误
3. 避免阻塞主线程
4. 实现错误边界
问题:
内存使用不当导致泄漏
错误示例:
- 事件监听器未移除
- 定时器未清理
- 闭包引用过多
- DOM节点引用未释放
解决方案:
1. 及时清理事件监听器
2. 清理定时器和间隔器
3. 避免不必要的闭包
4. 使用WeakMap/WeakSet
问题:
JavaScript动态类型导致错误
错误示例:
- 类型转换错误
- 未定义属性访问
- 参数类型不匹配
- 返回值类型不确定
解决方案:
1. 使用TypeScript
2. 添加JSDoc类型注解
3. 运行时类型检查
4. 使用PropTypes
