wtf is london_functional_scala?

This project, called london_functional_scala, is a stateful backend code playground, essentially a sandbox where you can write and run code in a live environment that remembers state between interactions. It is designed for experimenting with functional programming concepts in a hands-on way. The project has two parts: a backend and a frontend. The backend is built with Scala and started using a tool called sbt, which is standard for Scala projects. The frontend is built with Elm, a language that compiles into JavaScript for building web interfaces. You run a shell script to build the frontend, and a separate command to start the backend server. Beyond that, the README does not go into detail about what specific features the playground offers or how the two pieces communicate. This would appeal to developers learning or exploring functional programming, particularly those interested in how Scala and Elm work together. A coding bootcamp instructor might use it to let students experiment with functional concepts in a browser-based environment, or a developer curious about Elm could use it as a starting point for a larger application. The combination of a Scala backend with an Elm frontend is somewhat uncommon, making it potentially interesting for anyone evaluating that particular technology pairing. The README is minimal, so anyone considering this project should expect to dig into the source code itself to understand how it works, what it supports, and whether it is actively maintained. With only a handful of stars, it appears to be a small or experimental effort rather than a polished product.
