JSFiddle

JSFiddle provides a browser-based environment for experimenting with HTML, CSS, JavaScript, and supported web resources. Users can create examples, inspect a result, and share a reproducible demonstration.

The selected settings, external resources, account features, and sharing conditions determine the environment. A working example is not a complete production application. Users should avoid placing confidential code or data into a publicly shared demonstration and should check the relevant platform terms.

For related tasks, JSFiddle can be considered alongside GitHub for code repositories, issues and change reviews and MDN Web Docs for web platform documentation, html css and javascript references. These resources cover adjoining parts of the subject; each publishes its own information and handles its own service, access arrangements or applications.
