How do I select the element and change it

I am not sure how to get the p element and change its value to the inputValue var

app.js 
var inputValue = document.getElementById('linkText').value;
const info = document.getElementsByClassName('.info');
info.textContent = inputValue;
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>

When you use getElementsByClassName, the argument is just the class name (no period). You may have been thinking of using querySelector.

Also, that function returns an element collection instead of a single element, so you'd need to use indexing to select the first element of the collection: info[0].textContent = inputValue;
