ToolerWork Code Studio gives you a React JSX editor online for component practice, state demos, UI snippets, and frontend learning. The preview runs in a sandboxed browser frame.
function App() {
return <h1>Hello React</h1>;
}React preview renders the App component in a sandboxed browser tab.
JSX is transformed client-side and rendered as a small React component in an isolated frame. It is designed for focused snippets and learning tasks where a fast browser workspace is more useful than a full local project.
Start with the built-in project, replace its sample with one of these focused examples, and compare your result with the expected output.
Practice JSX mapping and stable keys in a small component.
function App() {
const tools = ["Python", "SQL", "React"];
return <ul>{tools.map((tool) => <li key={tool}>{tool}</li>)}</ul>;
}Expected: The preview renders a three-item list.
Try in editorUse a hook and event handler in the browser preview.
function App() {
const [open, setOpen] = React.useState(false);
return <button onClick={() => setOpen(!open)}>{open ? "Open" : "Closed"}</button>;
}Expected: The button label toggles on each click.
Try in editorYes. The editor loads React and Babel client-side to render an App component in preview.
No. This is for quick browser-based React snippets without project setup.
Yes. Starter code includes a useState example.
No. It is a fast component playground for small snippets and learning.
JSX is transformed client-side and rendered as a small React component in an isolated frame. The workspace also keeps the active project in local browser storage.
This playground does not include npm imports, routing, a bundler, or a multi-package React project. React and Babel are loaded from a CDN, so the first preview requires an internet connection.
