JavaScript JavaScript and the DOM (Retiring) Making Changes to the DOM Modifying Elements

I do not understand what this is asking. Am I supposed to add a variable called linkName? The ? does not ask that.

When submitting the prompt says "Bummer! the value of text input was not assigned to linkName". The question doesn't mention assigning anything to a variable called 'linkName'

let inputValue = document.querySelector('input#linkName').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>

Dale Severude why he should use getElementByID ? its ID its unique 1 per page or am i wrong ? so he can use anything :) and its more easyer then type getElementByID or other ones ....

let inputValue = document.querySelector("#linkName").value;

Ah yes, that passes the challenge as well. The challenge was referencing a video which uses getElementByID, so I thought that is what the challenge was looking for.

link has ID so you can also use querySelector("#link"), yea but he used in his example shorter way so i assum he is not new in JS and its easyer do it by querySelector :) one command for all .)
