What am I doing wrong?

There is probably something wrong but I can't find it, so can someone please help?

This is the task : Set the text content of the a tag to be the value stored in the variable inputValue.

app.js 
let inputValue = document.querySelector('a').textContent;
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>

Select the id with getElementById() . After the getElementById() use .value and store the input value inside the inputValue variable. Hope this help.

You probably said the right answer, same as Aakash Srivastav but I didn't get it really well because I needed some details.

I'm sorry. We don't write the ready code, so you can't learn. We are givin guidelines. Next time I try to pay more attention for the example. Happy coding!

Hey Nour El-din El-helw , they are saying to set the textContent of the anchor element to the value of input element which gets stored in inputValue variable..
What you are doing is - getting the textContent of anchor element.
The code will be - 

let inputValue = document.querySelector('#linkName').value;  // get the value of *input* element
document.querySelector('a').textContent = inputValue ;   // set the *textContent* of *a* to inputValue

Hope it helps :)
