What is the method for providing the event object as the second argument in a callback function?

edit

The method for providing the event object as the second argument in a callback function depends on the specific event being used. Typically, the event object is automatically passed as the second argument in many JavaScript event listeners, such as "click", "keydown", "submit", etc.

For example, for a "click" event, the parameter for the callback function might look like this:

function handleClick(event) {
  // code to handle the click event
}

Inside this function, the event object contains various properties and methods that provide information about the event, such as the target element, the type of event, and any data or parameters associated with it.

Other types of events may require different parameters or methods to access the event object, so it's important to check the documentation for the specific event being used.
