About

A persistent, offline, quasi-REPL for TypeScript that promotes coding with rapid feedback. Ideal for:

• Learning TypeScript itself.
• Experimenting with npm packages.
• Practising coding challenges.
• Demonstrating code.
• Building a 'functional core' independently of an 'imperative shell'.
• Modelling a domain, in isolation or interactively with a domain expert.

See also

• For a Node.js REPL, use the node command.
• For a Bun REPL, use the bun repl command.
• For online environments consider the official TypeScript Playground or another online environment.
• For a "REPL as document" notebook, consider Node.js Notebooks (REPL).
• To share code snippets, consider GitHub gist.
