HTML

<!-- Remember, you're not allowed to change the HTML! -->

<h1>Good Morning!</h1>

<form>
    <input type="text" id="new-text" placeholder="Type here..." />
    <input type="submit" value="Change" id="the-button" />
</form>

JavaScript

/*
 * Desired functionality:
 *
 * 1. User clicks on the "Change" button.
 * 2. If the text input is blank then nothing changes.
 * 3. The contents of the H1 element are replaced with the contents
 *    of the text input.
 * 4. The text input is cleared.
 * 
 * Use devdocs if you don't know the DOM API by heart!
