Playground Jump to heading

The playground and interactive code blocks format messages using the JavaScript implementation of MessageFormat 2, maintained by Eemeli Aro. Highlighting and other language features are powered by the MessageFormat 2 Language Server, maintained by Luca Casonato and Nicolò Ribaudo.

All validation and formatting of messages happens in your browser using the JS implementation and the language server (via WASM). No data is sent to any server.
