Playground

A place of your own for any JavaScript you want to try: no steps, no checks, nothing to follow. Change main.js, add files, break things. Your files live in the folder ~/playground and stay in this browser.

• Run (Ctrl+Enter, ⌘↵ on a Mac) runs main.js with node.
• The files panel adds, renames and deletes files and folders; main.js can import a file beside it (import { greet } from "./greet.js"). Ctrl+B (⌘B on a Mac) in the editor shows or hides it, Ctrl+P (⌘P) opens a file by name.
• The Terminal tab is a Linux shell: cd ~/playground, then node or anything else.
• Reset code in the ⋯ menu puts the starter main.js back and deletes every other file in the folder.
