Is there any easy way to find the correct answer when I can't figure it out (e.g. answer key or something like that)?

so... I run into this problem all the time. For some challenges I can't figure out the right answer and simply have to skip the challenge. It would be nice if Treehouse would provide an answer key somewhere...

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

onClick.sayButton = greeting; 
index.html
<!DOCTYPE html>
<html>
<head></head>
<body>
<button id="say">Say "Hello World!"</button>
<script src="app.js"></script>
</body>
</html>

You're on the right track, but you did it backwards.

What you wrote

onClick.sayButton = greeting; 

What it should be

sayButton.onclick = greeting;

For one, capitalization is very sensitive. onclick is all lowercase.

Secondly you did the dot notation backwards. Think of it as a possessive property: man's coat, baby's rattle, child's toy. Dot notation is just like that, but for programming: element.onclick.

More documentation and usage for onclick.

Good luck out there!
