Can't figure out how to pull text content from one element into another

This one has me stumped. How do I reference the <a> element in this syntax?

app.js 
var inputValue = document.getElementById("linkName").value(input.text);
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>

You can do this by 1st selecting the <a> anchor tag with JavaScript and use the .textContent property:

document.querySelector('a').textContent

and then you just assign it to the variable inputValue.

document.querySelector('a').textContent = inputValue;

You can use the document.getElementsByTagName('a') if you are more familiar with this method but don't forget that this method returns an array and you need to further specifies which <a> tag you want to select like this

document.getElementsByTagName('a')[0]

Remove the brackets and what's inside for value as it is not a function, but a string.

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