Using TypeScript Generics Properly in Practice

The article explains why TypeScript generics are needed and how they reduce type duplication while preserving type safety.

It covers the basics of using generics in functions, interfaces, type aliases, and bounded types with extends constraints.

Practical examples include API response wrappers and reusable utility function patterns.

Overall, generics are presented as a core TypeScript feature for maintainable shared utilities and accurate API-layer types.
