Did you declare a variable for the jQuery object with an argument of ".submit-btn"? I don't know what I'm doing wrong

Can someone help me find my mistake

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <button type="submit" class="submit-btn">Submit If You Can</button>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
 const $submit = $(".submit-btn").attr('disabled' , true);

You definitely have the right idea! However, you're chaining the method onto the variable $submit. This makes the variable less useful. If you call the variable and use the method on it later then the variable remains useful for other things in the future.

 const $submit = $(".submit-btn");
 $submit.attr("disabled", true);

If you didn't need to create a variable, you could chain it as follows with no issue:

$(".submit-btn").attr("disabled", true);

Keep in mind the challenge is asking for the variable. Hopefully this made sense and happy coding! :smile:
