自学编程遇到瓶颈怎么办？

遇到瓶颈是正常的。建议：1. 动手做项目 (Project-based Learning)，不要只看视频；2. 善用 AI 助手 (如 Cursor, ChatGPT) 解释代码和逻辑；3. 加入全球技术社区 (如 Discord, GitHub) 与他人交流；4. 拆解大问题为小模块逐个击破。

如何构建一个具备全球竞争力的开发者作品集 (Portfolio)？

优秀的 Portfolio 不在多而在精。包含 2-3 个完整的、已上线的项目 (Live Demo) 最佳。每个项目应包含：GitHub 源码链接、在线演示地址、以及一份中英文 Readme 文档说明解决了什么问题、使用了什么技术栈。
