> reuse objects Caching is often not such a bad idea regardless of GC.

• mikepurvis 5y ago
  Fair, but I think some GC'd languages (Java, JS) end up with a culture of boxed-everything where it's extremely easy to inadvertently throw off a ton of garbage from an inner loop, even doing operations that in other languages would only ever instantiate objects on the stack.

    Newer Java runtimes are very conscious of tight garbage creation loops, and will generally either unbox or perform some internal object pooling to avoid GC pressure. Value types (targeting JDK 18? or maybe already in 17) will give developers a tool to create new stack-allocated types for performance-critical sections as well

      Primitive types are not in java 17. Hoping to preview it on 18

        Seems unlikely, we are getting Loom before that. Don’t forget that we have been teased since 2014
