So close I can feel it (Selecting values and storing them in variables)

I can select the element but don't know how to select the value of input. Also trailed .innerHTML and textContent at the end of the querySelector to no avail. Please help!

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>
app.js 
let linkName = document.querySelector('input');

To get the 'value' of an input field ;)

let linkName = document.querySelector('input').value;

While you're around...

Set the text content of the a tag to be the value stored in the variable linkName

is the next assignment.

I did : 

input.value = a.textContent;

What's confusing me is that it's asking me to store it in a variable named the same as the one from the first test. I says I can't redeclare it.

Tried a few other things but I'm not quite understanding the question.

You need to do another query select to reference the anchor tag, then set its 'innerText' to the value from the previous challenge.

You are close! I think you just need to add '.value'

let linkName = document.querySelector('input').value;
