Choosing Your Stack: Languages at a Glance
When you direct an AI to build software, the language you pick still matters — a lot. The AI writes the code, but you live with the consequences: how fast you ship, how easy it is to , how often you hit a wall. The good news is that you don't need to master any of these languages. You need to know enough to make a sane choice and to recognize when the AI is steering you somewhere painful.
This chapter walks through the languages worth caring about, what each is genuinely good at, where it bites, and — crucially for vibe coding — how well AI assistants handle it. We'll end with a dead-simple guide for picking by goal.
A note before we start: AI assistants are much better at popular languages with mountains of public code than at niche ones. This isn't a small effect. It's often the single biggest factor in whether your project goes smoothly. Popularity is a feature. When a language and its main frameworks show up millions of times in public repositories, the AI has seen every common pattern, every typical error, and every idiomatic fix. When they don't, you're paying for that scarcity in failed attempts and confident-sounding nonsense.
