OH3: to use or not to use JS (ECMAscript 2021)

[Oliver2 (Oliver)]

[Rules DSL] Get item from string name!

Rules DSL also has a compilation delay on RPis (always has). Neither jRuby, Groovy, nor JRule have this problem. For JS there is evidence that running on a 64-bit OS using a 64-bit JRE or GraalVM reduces the compilation time by 10x. Writing JS rules without the Helper Library will also reduce this compile time, though interacting with the raw JSR223 APIs is pretty miserable. I would recommend any one of these over Rules DSL at this point.
