It's customary to use a onChange handler to listen for changes to input elements and save their values in state when designing a form with React components. A single onChange handler can be set up to handle multiple various inputs in the form, in addition to just one.

Making a controlled input is the first step in handling form inputs in React. You can accomplish this by allowing the component state to control the input. Then, depending on the input type, you give the state to the value or checked prop.

To handle form submission, we add a onSubmit event handler to the form, get the event object from the argument, and call event.preventDefault inside the handler so that we may run JavaScript code. We grab the name and value properties from event to handle multiple input changes with a single onChange handler.

In React, there are two sorts of form input. We have two types of input: uncontrolled and controlled. In that they remember what you typed, the uncontrolled inputs are similar to standard HTML form inputs.
