A Simple Form

Key Concepts and Functions:

1. useState:

   • The useState hook is used to create and manage the state of the form data (formData). It initializes the state with default values.

2. handleChange Function:

   • The handleChange function is called whenever there is a change in any form input. It updates the corresponding piece of state in the formData.

3. handleSubmit Function:

   • The handleSubmit function is triggered when the form is submitted. In this example, it prevents the default form submission behavior and logs the form data to the console. In a real application, you might send this data to a server.

4. Event Handlers:

   • The onChange event is used to trigger the handleChange function when the user types into any form input.
   • The onSubmit event is used to trigger the handleSubmit function when the form is submitted.

5. Input Elements:

   • Input elements (<input>) are used to collect user data. The value attribute is set to the corresponding piece of state, and the onChange attribute is set to the handleChange function.

Imagine a form where someone can enter their email address. In React, we use a function called useState to keep track of what the user types.
