JSOS is a hobby operating system whose kernel, C library, compiler, and JavaScript virtual machine are written largely in JavaScript, with C components. It is an experimental OS development project demonstrating JavaScript as a systems language.
Use cases
- run an operating system written in javascript
- study how to build a javascript vm for a kernel
- learn os development with a javascript userspace
- explore hobby operating system source code
- boot a minimal OS with a javascript interpreter
When to choose
- you want to study or hack on an unconventional JavaScript-based OS
- you are learning OS development and want a small readable codebase
- you need a JavaScript VM running bare-metal as a reference
When to avoid
- you need a production-ready operating system
- you require a permissive license for all components without review
- you need modern hardware support, drivers, or active development
