• For a REPL experience use the commandOpen Node.js REPL
  • Consider installing theJupyter extension for an enhance user interface (toolbars).
• For a notebook experience, create a file with the extension*.nnb, e.g.sample.nnb
  • Or use the menu itemNew File... to create a Node.js notebook

• Use the commandOpen a sample node.js notebook to open a sample notebook.
• Use the commandWelcome: Open Walkthrough... to checkout the samples.

• node.js >= 12
• node.js needs to be in the current path
