What are the benefits of using generics in TypeScript?

Generics in TypeScript provide a way to create reusable components that can work with any data type. This enhances code flexibility and type safety.

Can you give me an example of how generics improve type safety?

Sure! For instance, a generic function can accept any type of array and return the first element, ensuring the return type matches the input type.

What about performance? Do generics affect it?

No, generics do not impact performance. They are a compile-time feature, meaning they help with type checking but do not add overhead at runtime.

Are there any downsides to using generics?

One downside is that they can make code more complex and harder to read if overused. It's important to balance their use.

How do generics compare to other programming languages?

Generics are similar in concept across many languages, like Java and C#, but TypeScript's implementation is unique due to its integration with JavaScript.
