This chapter introduced you to event handling in React. The key differentiator between React and other approaches to event handling is that handlers are declared in JSX markup. This makes tracking down which elements handle which events much simpler.
You learned that having multiple event handlers on a single element is a matter of adding new JSX properties. Next, you learned that it's a good idea to share event handling functions that handle generic behavior. Context can be important for event handler functions if they need access to component properties or state. You learned about the various ways to bind event handler function context and parameter values. These include calling bind() and using higher-order event handler functions.
Then, you learned about inline event handler functions and their potential use, as well as how React actually binds a single DOM event handler to the document object. Synthetic events are abstractions that wrap native events; you learned why...
