BROWSER ERROR REPORTING

All of the major desktop web browsers—Internet Explorer/Edge, Firefox, Safari, Chrome, and Opera—have some way to report JavaScript errors to the user.

In all the previously mentioned browsers, they share a common path to accessing the web console. Perhaps the easiest way to view errors is to right-click on the web page, select Inspect or Inspect Element, and click the Console tab.
