Base9 is an educational language runtime and programming language! We’re using it to show people how to use Eclipse OMR to build their own language runtime with a Just in Time (JIT) Compiler! The base9 front-end language is a simple subset of JavaScript. For more information, visit the base9 website.

If you'd like to build your own language runtime, visit our guide on Building a Language Runtime!

This page contains some basic instructions to get you started. For more detailed instructions, go to:
