Finding the value?

How do I find the value? I'm also having a tougher time learning Javascript, so any help would be nice.

app.js
var inputValue = document.getElementById('linkName');

linkName.addEventListener('click', () => {
  myHeading.style = 'linkName.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>

Hi Alonzo! Looks like you saved the <input> element to inputValue so to get the value , just add .value to the end of document.getElementById('linkName') like so:

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

You can also save the element and value in separate variables in the case you need to use the <input> element somewhere else in your code:

var input = document.getElementById('linkName');
var inputValue = input.value;

Then, you can use the value by calling the variable name with no quotes wrapped around it. For example, say you want to update an <h1> element with the input value:

var h1 = document.querySelector('h1');
h1.textContent = inputValue;

I'm not sure if the rest of your JavaScript works based on this short snippet but I hope this helps you out some!
