What is this?
Build a shared notes list where multiple fake users add items — simulate with buttons, prepare for WebSocket later.
Why should you care?
Collaboration UIs need optimistic updates and conflict handling basics.
See it live — copy this example
Paste into an HTML file or the browser console (F12). Use Run below when the live editor is available.
<!DOCTYPE html>
<html><body>
<input id="text" placeholder="Note" /><button id="add">Add</button>
<button id="sim">Simulate teammate</button><ul id="notes"></ul>
<script>
const notes = [];
const authors = ["You", "Alex", "Sam"];
function render() {
document.getElementById("notes").innerHTML = notes.map(n =>
`<li><strong>${n.author}</strong>: ${n.text}</li>`).join("");
}
document.getElementById("add").onclick = () => {
const text = document.getElementById("text").value.trim();
if (text) { notes.unshift({ id: Date.now(), text, author: "You" }); render(); }
};
document.getElementById("sim").onclick = () => {
notes.unshift({ id: Date.now(), text: "Synced edit", author: authors[1+Math.floor(Math.random()*2)] });
render();
};
</script></body></html>Run Example »
Edit the code below and click Run to see the result in Toolliyo’s live editor.
What happened?
- unshift adds newest first.
- Each note shows author and time.
Practice next
- Add note for current user.
- Simulate other user button adds random author.
- Discuss WebSocket sync next step.
- Disable Add when input empty with button disabled attribute.
- Show relative time with toLocaleTimeString on each note.
Remember
Shared list data model Optimistic UI preview WebSocket as next step
ScriptVerse team notes
Shared notes list prototype prepares for real-time WebSocket collaboration layer.
Outcome: Collaboration UIs need stable ids and optimistic update patterns.
