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

I've looked at a lot of the comments regarding this question, and can't understand why my code doesn't work. Please could someone enlighten me! Thanks very much.

app.js 
let inputValue = document.getElementById('linkName').value;
let link = document.getElementById('link').textContent;
inputValue = link;
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>

hey Octavia,

let me just show you the code i used first

let inputValue = document.querySelector('#linkName').value;
let a = document.querySelector('a');
a.textContent = inputValue;

Regarding the second line, the reason why your code doesn't work is because you have the '.textContent' at the end of the selector, and it won't be able to select that. Instead, put 'link.textContent' on your third line. Also, because you need to 'Set the text content of the a tag to be the value stored in the variable inputValue', the 'inputValue' needs to be on the right side of the equal sign since the text content of the 'a' is being stored into 'inputValue'. The left side of the equal sign always goes into whatever is on the right side of the equal sign. Hope that helps!

Cheers, Joseph

Hi Octavia,

In line number two, you don't want to capture the links textContent, you just want to select the link element itself.

let link = document.getElementById('link');

In line number three, you want to set the textContent of the link to the value captured in your first line.

link.textContent = inputValue;
