We will create a simple component that acts as a Wizard or Multi Step, a component that allow to navigate among the children items rendering just one at a time. The navigation is done by using button to go back and forward.
This implementation requires to handle a simple state that define what element should be rendered: an index.
In this example we can see the use of
useState and how to use the functional form of the updater function to access the actual state and update it.
