What are the different types in React with TypeScript?

In React with TypeScript, you can use various types such as 'string', 'number', 'boolean', and custom types for props.

Can you explain how to define props types in a functional component?

Sure! You can define props types by creating an interface and then using it in your functional component like this:

interface MyComponentProps {
  title: string;
  count: number;
}

const MyComponent: React.FC<MyComponentProps> = ({ title, count }) => {
  return <h1>{title} - {count}</h1>;
};

What about state types in class components?

In class components, you can define state types by creating an interface for the state and using it in the class like this:

interface MyComponentState {
  count: number;
}

class MyComponent extends React.Component<{}, MyComponentState> {
  state: MyComponentState = { count: 0 };

  render() {
    return <div>{this.state.count}</div>;
  }
}

Are there any best practices for using types in React?

Yes! Some best practices include using interfaces for props and state, avoiding 'any' type, and leveraging TypeScript's utility types.
