Ruby Sandbox (WebAssembly)

Visit the Ruby Sandbox Kanban board. I've made the board public so everyone can see the tasks, plans, and thoughts on the project.

This project is under active development; the README will be updated as the project evolves. Inspired by Ken H. Burres III's Python Sandbox Turtle Mode, I wanted to build a similar experience for Ruby. Before diving into the "turtle" implementation, my primary focus is on establishing a solid Ruby sandbox environment.

A single-page Ruby sandbox environment using Monaco Editor and Ruby WASM (WebAssembly).
