Wanted a full JS coding playground I could run offline as I'm learning javascript, so I got this built in pure HTML + JS using Monaco Editor.
Features
Monaco-based editor with JS syntax + formatting
Custom console output (log/warn/error/info)
Run code in a safe iframe (no eval)
Theme toggle (light/dark)
Save/load to localStorage
Works entirely offline, no backend
Also shows runtime errors and stack traces properly inside the console view. You can Ctrl+Enter to run, clear console, or auto-format. And it's just one .html file. Definitely overkill for personal use, but surprisingly fun to build. If you're into building offline tools or like exploring what you can do with Monaco, happy to share or improve this further.
Would love feedback or any feature ideas (like maybe multi-language support? file system save/load).
I am practicing on FCC right now. But is not able to practice everyday since our internet was cut as we did not have the budget for it(medical and im going back to college). Many says to code everyday, but I cannot practice coding everyday since I cannot access FCC without internet.Im asking for advice on how I can code everyday using Javascript without needing Internet.
I am not American or from America if that matters.
