What are the best practices for using types in React?

When using types in React, it's essential to leverage TypeScript for type safety. This includes defining props and state types, using interfaces, and ensuring components are typed correctly.

Can you give me an example of how to define prop types?

Sure! You can define prop types using TypeScript interfaces. For example:

interface MyComponentProps {
  title: string;
  isActive: boolean;
}

const MyComponent: React.FC<MyComponentProps> = ({ title, isActive }) => {
  return <h1>{isActive ? title : 'Inactive'}</h1>;
};

What about using default props?

You can set default props in TypeScript by using the defaultProps property. For example:

MyComponent.defaultProps = {
  isActive: false,
};

Are there any tools to help with type checking?

Yes! You can use tools like ESLint with TypeScript plugins, and the TypeScript compiler itself provides excellent type checking.
