three-versions-types

When working with TypeScript types, three versions must align: the version of the package you're using, the version of its type declarations (@types), and the version of TypeScript itself. Misalignment between these versions can cause confusing type errors even when the code works at runtime.

Understanding these three versions helps diagnose and prevent type compatibility issues.

Keep package, @types, and TypeScript versions compatible. Update them together to avoid mysterious type errors.

在发布类型声明时使用。在处理版本冲突时使用。当库有类型时使用。在管理 @types 包时使用。在调试类型不匹配时使用。 来源：marius-townhouse/effective-typescript-skills。
