Help with the DOM

I need to set the text content of the a (<a>?) tag to the inputValue var. Can someone please help me understand how to go about doing this?

let inputValue = document.querySelector('a').textContent;
<!DOCTYPE html>
        <title>DOM Manipulation</title>
    <link rel="stylesheet" href="style.css" />
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href="https://teamtreehouse.com"></a>
        <script src="app.js"></script>

Hey so from the code you posted I see an input and an anchor tag in the html :

<input type="text" id="linkName">
<a id="link" href="https://teamtreehouse.com"></a>

If I'm understanding your question correctly you want to use the input value as the anchor tag's text? if so it would look like this:

// this will grab the value inside of the text input
let inputValue = document.querySelector("#linkName").value;
//this will set the text content of the anchor tag
document.querySelector('#link').textContent = inputValue;

The challenge its telling you to set the text content of the a tag with the value you have already stored in the variable inputValue. So you need first to select the only a tag element there is. And then you need to change its text content with the value stored previously in the inputValue variable. It should be something like this.

let inputValue = document.querySelector("input").value;
const a = document.querySelector("a");
a.textContent = inputValue;

Hope it helps!
