Babel includes JSX processing.

Add External Scripts/Pens

Add Packages

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 active, Pens will autosave every 30 seconds after being saved once.

Auto-Updating Preview

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

If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.
