Below we follow the canonical counter component example provided in the React documentation. It's a pretty simple demo that contains a button inside of a Counter component. Once clicked, it advances the state by one and updates the state.count for rendering purposes.,Let's see a code demo of this pre-context era example.,In the Context API demo above, we saw a way to share data through many components using “prop drilling.” This is a valid option, but in some situations, it feels clunky. For better composition, we will use the Context API.

That example attaches a handler to the button node. Clicks on the button cause that handler to run, but clicks on the rest of the document do not.,When that works, extend it to style the button for the currently selected tab differently so that it is obvious which tab is selected.,If two clicks happen close together, a "dblclick" (double-click) event also fires, after the second click event.
