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.

在發布類型聲明時使用。在處理版本衝突時使用。當庫有類型時使用。在管理 @types 包時使用。在調試類型不匹配時使用。 來源：marius-townhouse/effective-typescript-skills。
