In JavaScript's addEventListener() method, the ' E ' refers to the event object that is passed to the event listener function when the event occurs .

The event object contains information about the event that occurred, such as the type of event, the target element that triggered the event, and any additional data associated with the event.

For example, suppose you have a button element in your HTML code, and you want to add an event listener to it to listen for the 'click' event:


<button id="myButton">Click me</button>

You can add an event listener to the button using the addEventListener() method:


const button = document.getElementById('myButton');
button.addEventListener('click', handleClick);

function handleClick(event) {
  // Handle the event here
  console.log('Button clicked!');
  console.log('Event object:', event);
}

In this example, the handleClick function is passed the event object as a parameter when the button is clicked. The event parameter can be used to access information about the event, such as the type of event, the target element, and any additional data associated with the event.

By accessing the properties and methods of the event object, you can perform various actions in response to the event, such as updating the UI, making an API call, or navigating to a new page.
