Welcome!
Nova is a JavaScript (ECMAScript) and WebAssembly engine written in Rust and following data-oriented design principles. It is currently nothing more than a fun experiment to learn and to prove the viability of such an engine, but may very well become something much more in the future.
The engine is still very limited in it's capabilities only passing about 48% of the test262 test suite. However development is ongoing and we are quickly improving the engine. If you are interested in the project, please check out the GitHub repository and or join our Discord server where the core team resides and where we discuss development.
