How can I improve form validation in my web application?

You can enhance form validation by using both client-side and server-side validation techniques. Would you like to know more about each?

Yes, please explain client-side validation.

Client-side validation involves checking user input before it is sent to the server. This can be done using JavaScript to ensure fields are filled out correctly, like checking for valid email formats or required fields.

What about server-side validation?

Server-side validation is crucial as it verifies the data after it has been submitted. This ensures that even if client-side validation is bypassed, your server checks the data for correctness and security.

Are there any libraries you recommend for form validation?

Yes! Libraries like Formik and Yup for React, or Validator.js for general JavaScript, are great for implementing robust form validation.
