The .removeEventListener() method is used to reverse the .addEventListener() method. This method stops the event target from “listening” for an event to fire when it no longer needs to. .removeEventListener() also takes two arguments:

1. The event type as a string
2. The event handler function

Check out the syntax of a .removeEventListener() method with a click event:

eventTarget.removeEventListener('click', eventHandlerFunction);

Because there can be multiple event handler functions associated with a particular event, .removeEventListener() needs both the exact event type name and the name of the event handler you want to remove. If .addEventListener() was provided an anonymous function, then that event listener cannot be removed.
