Why isnt this working

let button = document.getElementyById('sayPhrase'); let input;

button.addEventListener('click', () => { alert(input.value); });

js/app.js 
let button = document.getElementyById('sayPhrase');
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>
