TOPIC OVERVIEW

Write reusable code that works with different types without throwing type safety out the window.

18 QuestionsAdvancedHigh Priority ~15 min read

Generics let you write code that works with different types while still remembering exactly what those types are. Instead of using any and losing type information, you can make the type itself a parameter.

You will see generics throughout TypeScript, especially in arrays, promises, API utilities, reusable components, and libraries. Understanding generics helps you write flexible code without sacrificing type safety.
