- setting back the correct key names? Try first getting the <code>div</code> with
- <code>id="piano-keyboard"</code>, then get the <code>childNodes</code> from it.
- Once you have the NodeList containing the <code>childNodes</code>, you can
- add the correct key names modifying the <code>innerText</code> property of each
- element in the list. Finally print the NodeList to the console for us to evaluate it.
- For example:
- <pre><code>
- let pianoDiv = /* Get the div with id="piano-keyboard" *
- let keys = /* Get the child nodes of pianoDiv */
- /* Modify the innerText of each element in the list by setting the correct note */
- console.log(keys);
- </code></pre>
- If your code is correct, the notes will appear in the keys.
- Testing with the dev tools console on the exercise itself might not give the
- expected results and might also break the grading. For this reason we advise
- you to copy the following code into an empty HTML file, and test your solution
- in there by opening it within with the browser and using the developer tools
