Can't figure out how to get the value of the text input element.

Here's the goal - Get the value of the text input element, and store it in a variable linkName

Here's the error - Bummer! You selected the element, but have not gotten the value.

I think I want to get the a href value. I tried the attached code, but it doesn't work. What am I missing?

I also tried a lot or other permutations, but none of them worked either, so now I'm stumped.

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');
linkName.textContent;

Your error message has a very good hint!

The message "Bummer! You selected the element, but have not gotten the value." is spot-on. When you use querySelector you get the element itself, but what you really want is the value property of that element.

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

I had forgotten that you could add a dot value after the querySelector. Thanks for the reminder.

JavaScript makes this extremely simple. when you're used to things like "innerText" and "innerHTML" you might miss it.

let linkName = document.querySelector('input').value; // <-- Voila!
// linkName now contains whatever the user typed into the input field

You'll use value a lot, so it's worth committing to memory, but if you ever forget property or method names in JavaScript, don't hesitate checking with documentation like MDN. Half of being a good developer is knowing where to find the things you don't know.
