Basically an event handler is block of code waiting for an action to execute the code within. For example: 

$( "#target" ).click(function() {
  alert( "Handler for .click() called." );
});

When the user clicks on the target that the listener was placed the code inside the function will run. It will run EVERY time the target is clicked.

I hope this helped clear it up slightly! Happy Hacking!

Event Handler is the call back function. Please refer to this course. https://teamtreehouse.com/library/listening-for-events-with-addeventlistener
