JavaScript styling in lesson "Styling Elements" incompatible with Safari 10?

So I have tried following along exactly as the instructor does, and even after many failed attempts, downloading his files, and neither works in the latest version of Safari (10.1.1) for me on my MacBook Pro (OS Sierra 10.12.5.

I also have a Windows PC that I can preview in multiple browsers such as IE, Chrome, Edge via the text editor I'm using (Dreamweaver). The hide/unhide styling works perfectly for Chrome and Edge, but IE and Safari are unresponsive to this styling.

Am I doing something wrong or is this technique just incompatible with Safari at the moment?

<!DOCTYPE html> <html> <head> <title>JavaScript and the DOM</title> <link rel="stylesheet" href="css/style.css"> </head> <body> <h1 id="myHeading">JavaScript and the DOM</h1> <p>Making a web page interactive</p> <button id="toggleList">Hide list</button> <div class="list"> <p class="description">Things that are purple:</p> <input type="text" class="description"> <button class="description">Change list description</button> <ul> <li>grapes</li> <li>amethyst</li> <li>lavender</li> <li>plums</li> </ul> </div> <script src="app.js"></script> </body> </html>

const toggleList = document.getElementById('toggleList'); const listDiv = document.querySelector('.list'); const input = document.querySelector('input.description'); const p = document.querySelector('p.description'); const button = document.querySelector('button.description');

toggleList.addEventListener('click', () => { if (listDiv.style.display == 'none') { toggleList.textContent = 'Hide list'; listDiv.style.display = 'block'; } else { toggleList.textContent = 'Show list';
listDiv.style.display = 'none'; }

button.addEventListener('click', () => { p.innerHTML = input.value + ':'; });
