I have re-watched the previous videos numerous times and I just can't quite wrap my head around it.

I am stuck on the first part of the challenge and for some reason I just can't seem to get my head around, I feel like I'm close. I have re-watched previous videos linked to this task, I have searched for things like this.

https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector

but to no prevail.

please sign post me :)

app.js 
const inputValue = document.querySelector('input. value');
index.html 
<!DOCTYPE html>
<html>
    <head>
      <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
      <div id="content">
        <label for="linkText">Link Text:</label>
        <input type="text" id="linkText" value="sample text">
        <p class="info"></p>
      </div>
    <script src="app.js"></script>
  </body>
</html>

The argument to querySelector (and querySelectorAll) is a selector string like you would use in CSS. The result will be a reference to the selected element. Then, to get the value of that element, you would use .value to get to the property itself:

const inputValue = document.querySelector('input').value;
