What do I type in?

I can't figure out what they are saying to put down in the app.js. What do I need to type in? Thanks!

js/app.js 
let button;
let input;

button.addEventListener('click', () => {
  alert(input.value);
});
index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Phrase Sayer</title>
  </head>
  <body>
    <p><input type="text" id="phraseText"></p>
    <p><button id="sayPhrase">Say Phrase</button></p>
    <script src="js/app.js"></script>
  </body>
</html>

It's asking you to complete line 1 of the program. So, let button = ...;

And set it equal to the element with the ID of sayPhrase.

Hope that helps.
