Babel includes JSX processing.

Search for and use JavaScript packages from npm here. By selecting a package, an import statement will be added to the top of the JavaScript editor for this package.


Auto Save

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.
