The anchor tag's text content does not contain the correct value.

Why?

Please can you explain me in details?

app.js 
let inputValue = document.getElementById('linkName');
let aTag = document.querySelector('a');
inputValue = inputValue.value;
aTag.innerText = inputValue.value;
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>

In line three:

inputValue = inputValue.value;

You set the inputValue variable to contains it's value, that means that is is now just a regular string variable containing whatever inputValue's value property contained.

So when you reference inputValue.value on line 4 that's invalid as pure strings (which the inputValue now is) does not contain a value property. You can fix this issue by simply removing the .value like this:

let inputValue = document.getElementById('linkName');
let aTag = document.querySelector('a');
inputValue = inputValue.value;
aTag.innerText = inputValue;

Then you'll be able to pass the challenge.
