✨This talk was recorded at ElixirConf EU 2024. If you're curious about our upcoming event, check https://elixirconf.eu ✨ Without libraries, we’ll see how we can leverage Elixir specificities to easily tokenize, parse, print and interpret a toy language with a few recognizable features (variables, primitive types, closures). Adding OTP and Phoenix LiveView to the mix, it evolves towards a quirky stateful computation system with basic graphical editing of programs.
