How can I use TypeScript generics in my React components?

You can use TypeScript generics in React components to create reusable and type-safe components. For example, you can define a generic component that accepts props of different types.

Can you show me a simple example of a generic component?

Sure! Here's a basic example:

import React from 'react';

interface Props<T> {
  items: T[];
  renderItem: (item: T) => React.ReactNode;
}

const GenericList = <T,>({ items, renderItem }: Props<T>) => {
  return <ul>{items.map(renderItem)}</ul>;
};

In this example, GenericList can render a list of any type.

What are the benefits of using generics in React?

Using generics allows you to create components that are flexible and reusable, while also ensuring type safety. This helps prevent runtime errors and improves code maintainability.
