Personally I feel JITs have gotten too much hype. While they have some advantages in optimization, it seems far outweighed by the downsides. I’d rather have an interpreter for development and a static compiler for production.

The JIT involved is really a static compiler that has been adapted for use as a JIT compiler: https://llvm.org/docs/ORCv2.html
