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

I'm slightly confused, my solution to this problem was the following but it doesnt work

let inputValue = document.getElementById('linkName'); let a = document.getElementsByTagName('a');

inputValue = a.textContent;

app.js 
let inputValue = document.getElementById('linkName');
let a = document.getElementsByTagName('a');

inputValue = a.textContent;
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>

There a few issues here:

  • At the moment, inputvalue contains an element instead of a value
  • the top line should remain as it was when you passed task 1
  • getElementsByTagName returns a collection, not a single element
  • you might want to use getElementById again instead
  • in an assignment, the thing you are assigning to goes on the left side of the "="
