When you develop a web application is good practice don't mix the presentation with the logic. In our case, the HTML contains the presentation while the JS file contains the logic. When we add events in the HTML file we're adding logic to the presentation layer. For this motive, is a good practice to move the events to the JS file. This video shows how you can get to this goal. When you change your code, you must be careful to avoid the error "uncaught type error cannot read property 'addeventlistener' of null".
