If the code JITs well What does this mean? Any JIT can make a tight loop of math and arrays run well but that doesn't mean a typical program runs well.

- kenhwang 2y agoFor Ruby, it's code where variables and method input/return types can be inferred to remain static, and variable scope/lifetime is finite. From my understanding, much of the performance gain was from removing the need for a lot of type checking and dynamic lookup/dispatch when types were unknown. So basically, writing code similarly to a statically typed compiled language.
