 ## Conclusion
 
+Events and event handling is vital to web programming with the addition of the language to browsers. 
+JavaScript allows for dynamic page rendering, and user can interact with the contents of the page
+in real time. With knowledge of these basic techniques, you'll become comfortable working with more
+complex interactions like those in video games that you may have played or seen before!
