Nova JavaScript engine
Independent JavaScript engine written in Rust
Nova is a JavaScript engine exploring a different, data-oriented design inspired JavaScript engine design. This design allows greatly reduced memory usage, optimal data cache locality for algorithms on happy paths, memory safety by construction, and various other technical optimisations that together form a compelling and interesting whole. The design involves tradeoffs, paying extra indirection for its gains, and the implementation treads mostly unfamiliar territory: the technical choices are nothing new, but they have not seen wide usage in production JavaScript engines to date. If the upsides overshadow the downsides, as they seem to do, the result will be a JavaScript engine that reduces memory usage by 30 to 50 percentage points, while improving performance under real-world loads.
