I didn't find any event keyword in your code.

onclick is an HTML attribute that allows JavaScript to listen for click events on the element.

Your program does not work. event.target is only available if your event handler has at least one parameter.

Look at this code I created

I have used addEventListener to add my event listener. That enables me to pass my load function has a callback instead of calling it manually. When using addEventListener, your event listener first argument is an Event object.

This old chapter from a book published in 2009 talks about the event object.

Note that the first parameter, event, can be named anything. Which means that the below code will work

function load (e) {
e.target.innerHTML = "...";
}
