JavaScript JavaScript and the DOM (Retiring) Making Changes to the DOM Modifying Elements

JS and the DOM. I need help to solve an exercise.

Select the <input> element with the ID linkName and store its value in the variable inputValue. (For a refresher on getting the value of a text input, watch this video from the previous section.)

I tryied do figure it out in two ways:

var inputValue = document.getElementById('linkName');

and

var inputValue = document.querySelector('input');

and it isn't work. Why?

app.js 
var inputValue;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href="https://teamtreehouse.com"></a>
        </div>
        <script src="app.js"></script>
    </body>
</html>

I'd just solved it. The answer is:

const inputVal = document.getElementById('linkName');
var inputValue = inputVal.value;
