>Servo [0] and Stylo [1] are both production-ready browser scripting and styling engines implemented in Rust.
Servo is absolutely not production ready. A couple of particular pieces of Servo, such as Stylo and WebRender, can be considered production-ready, but no so much the project as a whole.
Servo uses Firefox's SpiderMonkey, which is written in C++, as its JavaScript implementation.
Servo is an experimental project designed to build and test components that can be integrated into Firefox. It relies on Gecko for JS.
