I don't understand how to set the content of a tag as value of a variable.

It says: ''The anchor tag's text content has not been set.''

app.js 
const inputValue = document.getElementById('linkName').value;
inputValue.attribute('a').content;
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>

Task 2 is kind of like task 1 in a mirror. You'll still want to use a selector function to identify the element, but instead of the "value" attribute you'll want to access the "textContent". And all that will be on the left side of the assignment this time, with "inputValue" on the right side providing the value to set.

Should I use the element.attribute property?

I added this, but it says that the anchor tag's text content has not been set.

document.getElementById('linkName').content = inputValue.attribute

I don't think elements have an "attribute" (singular) property. They have an "attrributes" (plural), but you won't need it here. The only attribute you need for task 2 is "textContent".
