'assign the greeting event handler to the click event on the sayButton.' What am I supposed to enter here??

How does one answer this question???

var sayButton = document.getElementById("say");
var greeting = function() {

}
sayButton.onclick(greeting);

  <head></head>
  <body>
    <button id="say">Say "Hello World!"</button>

Try like that.

var sayButton = document.getElementById("say");
var greeting = function() {
  alert("Hello World!");
}

sayButton.onclick = greeting;
