What are the best practices for handling forms in React with TypeScript?

When handling forms in React with TypeScript, it's important to define types for your form data, use controlled components, and manage validation effectively.

Can you explain what controlled components are?

Controlled components are form elements whose value is controlled by React state. This allows for better control and validation.

How do I handle form validation in TypeScript?

You can use libraries like Yup or React Hook Form to handle validation. They integrate well with TypeScript and provide type safety.

What about managing form submission?

For form submission, you can define a submit handler that processes the form data. Make sure to prevent default behavior to avoid page reloads.

Are there any common pitfalls to avoid?

Yes, common pitfalls include not managing state properly, neglecting accessibility, and failing to handle asynchronous validation.
