✓ 应当这么做
- ✓ Enable strict mode everywhere and treat TypeScript strict flags as non-negotiable in new files
- ✓ Handle every promise: await it, return it, or attach a .catch with a real recovery path
- ✓ Model uncertain data as `unknown` and narrow it with type guards before use
✕ 常见反模式
- ✕ Floating promises (async calls fired without await or catch)
- ✕ `any` casts used to silence a type error instead of fixing the shape
- ✕ Mutating function arguments or module-level objects from shared scope
◎ 交付前验证
- ◎ Typecheck (`tsc --noEmit` or equivalent) passes with zero errors
- ◎ Lint passes and no rule was disabled inline
- ◎ Node/browser runtime compatibility checked against the project engines field
