useState() is a commonly used hook in React, and is necessary in adding functionality to many different feature. useState() allows you to add a state variable to your component.

Now that useState() is imported, we can call useState at the top level of our component to declare a state variable. Using array destructuring, we declare both a state variable, as well as a set function.
