Rhai is simple and similar to JavaScript+Rust with dynamic typing. According to tests performed, it proved to be quite efficient, achieving 1 million iterations in 0.3 seconds on a single-core 2.3 GHz Linux VM.

It has tight integration with native Rust functions and types, including getters/setters, methods, and indexers.
