TypeScript generics are one of the most powerful features of the language, enabling developers to write flexible, reusable code while maintaining type safety.
What Are Generics?
Generics allow you to create reusable components that can work with multiple types rather than a single one. Think of them as variables for types.
Basic Syntax
function identity<T>(arg: T): T {
return arg;
}Real-World Applications
Generics are everywhere in modern TypeScript codebases. From React hooks to API clients, understanding generics is essential for any serious TypeScript developer.
