Need help.

Challenge Task 1 of 2

Store the value of the text input element in the variable inputValue. (If you need a refresher on getting the value of a text input, this video from the previous section demonstrates how.)

app.js 
let inputValue = document.getElementById ("input");
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>

What you did is you stored the input element into the variable inputValue. The challenge wants you to store the value of the input element, this is achieved using the .value-property of your input element:

let inputValue = document.getElementById("linkName").value;

Is this also valid?:

let inputValue = document.getElementById('linkName').textContent;

I have just tried your code babasariffodeen and it returns an error. So i'd say no.

I have linked the definitions of both textContent and value definitions that may help clear things up between the two differences.

This challenge want that you store the value of the input element. So you gonna use the ID's name and use the attribute value.

let inputValue = document.getElementById("linkName").value;

I know this is old but the answer is:

let inputValue = document.getElementById('linkName').value;

Good Luck all ;)

"linkName" is not a valid selector, your code won't know what "linkName" is. What you take as a selector is basically the same one you would use if you'd append a certain styling with css to it: In this case, you'd use the selector "#linkName", as your element has the ID of "linkName". querySelector would work if you used "#linkName" as selector.
