In any application, not just Javascript based ones, user input is one of the foundational pieces for user interaction with the application, the server, and with others across the web. In order to capture user input, you need forms. In this episode, we’ll explore the box form support provided by React with the basic HTML form elements like input, textarea and select, as well as libraries that have been developed to enhance form creation, as well as to perform validation.
