What is Vibe Coding? Simply put, it's "writing code with natural language" — you describe what you want in Chinese or English, and AI generates the code for you. This has completely changed the rules of the software development game. But here's a key question: AI can help you write code, but AI can't think for you. You still need to know "what to write," "why to write it this way," and "how to judge if it's correct." This is exactly the foundational cognitive framework this chapter will help you build.What is Vibe Coding?

AI can help you write code, but the following abilities are irreplaceable by AI: - Judgment: Knowing whether AI-generated code is correct and good - Architecture thinking: Knowing how to design systems and divide modules - Domain knowledge: Understanding business logic and knowing "what to build" - Debugging ability: Knowing where to investigate when problems ariseAI can help you write code, but the following abilities are irreplaceable by AI: - Judgment: Knowing whether AI-generated code is correct and good - Architecture thinking: Knowing how to design systems and divide modules - Domain knowledge: Understanding business logic and knowing "what to build" - Debugging ability: Knowing where to investigate when problems arise

Don't try to learn everything at once. Pick one direction to go deep first, establish a "base camp," then expand horizontally. Full-stack doesn't mean "knowing a little about everything" — it means "having one core strength while being functional in other areas."Don't try to learn everything at once.

You can write webpages with plain HTML/CSS/JS, so why learn frameworks like React and Vue?You can write webpages with plain HTML/CSS/JS, so why learn frameworks like React and Vue?
Core reason: When pages become complex (like Taobao or WeChat web version), directly manipulating page elements one by one becomes very messy. Frameworks help you "manage complexity."Core reason: When pages become complex (like Taobao or WeChat web version), directly manipulating page elements one by one becomes very messy.
