Underlying technologies

The code is actually quite simple. It's based on:

• Ace for the code editor
• React for the UI
• Redux for the state
• Web Workers for running the code

Note on security

This is not designed to be a secure coding environment. The code you type is run inside a Web Worker, but breaking out of the sandbox or at least creating unexpected behaviour is totally doable (e.g. by calling postMessage).
