I get stuck with javascript
var button;
var input;
button.addEventListener('click', () => {
alert(input.value);
}
let input = document.getElementById("phraseText");
let button = document.getElementById("sayPhrase");
console.log (button);
});
<!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>

- "button" and "input" are already declared on the top two lines, so don't use "let"
- you must assign the values before the call to "addEventListener"

Remove the last two lines.

231,248 PointsBoth the "var" and "let" keywords declare variables, so if you say "
var button" and then later "let button ...." that's declaring it twice. But you can have "var button" at the top and later assign it "button = ...".And the code that calls "
button.addEventListener..." depends on "button" already having a value, so the assignment must be done before that line instead of after it.
