It’s for example important when debugging a web page to see how many submit events a form element sends out.
With this debugging method you prevent sending and tracking browser events multiple times.
There is a handy API in Chrome developer tools that makes this easy.
If you want to stop listening for events again, you simply use:
Example: Log all click events of the window object to the console
Now with this helpful debugging tool in our toolbox, we can for example select a form element in Chrome developer tools to start monitoring submit events.
After you select the element in the elements tab, Chrome Dev Tools will show a little $0 sign next to it.
