Build the workshop itinerary

The studio demo kept one array as its source of truth. Apply that pattern to the community workshop planner; the starter already has two session objects and an empty list.

For example, a different page could create one library notice from state:

javascript
const notice = document.createElement("p");
notice.textContent = `Due: ${loan.dueDate}`;
document.querySelector("#notices").append(notice);

The notice is not the workshop solution: your itinerary needs a loop, a rerender, and a button listener. Run the starter first; the list is empty. Edit script.js and check the preview after each step. For the text-safety check, temporarily give the second session a title containing <em> characters and rerender; restore the title afterward so the next lesson begins with the ordinary Repair café entry.

Your Task

  1. Implement and call renderSessions() to render two #sessions li rows at load, one for each session, showing its time and track.
  2. In that renderer, include session titles as literal text; a title like <em>Repair café</em> must display its brackets without creating an em element.
  3. Wire the update button to change the first time to 10:00 and rerender without adding duplicate rows.

After the update, two rows should still appear and the first should read 10:00.
