Stuck in task 2 in this exercise of "DOM scripting by example"

This is the tongue of the question of task 2:

"Alter the callback function to use the event object. Using the event object, ensure that the browser's default form submit behavior does not occur when the form is submitted".

https://teamtreehouse.com/library/dom-scripting-by-example/adding-and-removing-names/using-the-submit-event

I think I missed from the video what is the "Event object". I know what is and event and what is an object, but I might missed the particular meaning of "event object". I did try to use preventDefault() inside the event handler row, but without success.

"Event object" means Event has so many properties. For example, click event, keydown event,

event also has DOM element. For more read: https://www.w3schools.com/jsref/dom_obj_event.asp

What meant on that questions: 

const form = document.querySelector('form');
const submitButton = form.querySelector('[type=Submit]');

form.addEventListener('submit', (e) => {
  e.preventDefault();
});
