Frequently asked questions

Offline JS Playground runs JavaScript in the browser, so it supports modern ES6+ syntax, including arrow functions, classes, and template literals. However, it cannot import external modules or use Node.js‑specific APIs, as it operates purely in the client environment.
Offline JS Playground stores snippets locally in your browser’s storage, so they are only available on the device where you created them. There is no built‑in sync feature, but you can copy and paste code between browsers manually.
Offline JS Playground is designed as a Chrome extension, so it works best in Chrome. While it may run in Chromium‑based browsers like Edge or Brave, full compatibility is guaranteed only on Chrome, and other browsers may lack the required extension APIs.
