What are the differences between generics and interfaces in TypeScript?

What are the differences between generics and interfaces in TypeScript?

Generics allow you to create reusable components that can work with any data type, while interfaces define the structure of an object.

Can you give me an example of how to use generics?

Sure! Here's a simple example: function identity<T>(arg: T): T { return arg; } This function can take any type and return it.

And how would an interface look in this context?

An interface could be defined like this: interface Person { name: string; age: number; } It describes the shape of a Person object.

When should I use generics instead of interfaces?

Use generics when you need flexibility with types, and interfaces when you want to define a specific structure.
