Is the JVM a upside or downside to Scala?

• scala-cli

  34 504 9.7 Scala

  Scala CLI is a command-line tool to interact with the Scala language. It lets you compile, run, test, and package your Scala code (and more!)

  

Have you tried Scala CLI? It has been proposed to be a default Scala command. Here is some more motivation behind it.

• Flutter

  1,203 161,805 10.0 Dart

  Flutter makes it easy and fast to build beautiful apps for mobile and beyond

  

Google also tried to make Dart and Flutter happen, but that supposedly multiplatform UI toolkit still has terrible performance when rendered to the web (e.g. using 10% of the CPU to render a blinking cursor). Google does not seem to take non-Android Flutter use cases seriously, so relatively few people care for it or trust it enough to use it.

• mimalloc

  35 9,447 9.1 C

  mimalloc is a compact general purpose allocator with excellent performance.

  

Yes, it's very efficient and that's not where the main problem lies. However, small allocations with modern C heap allocators like mimalloc or snmalloc has gotten extremely efficient as well. Would be interesting to see a benchmark comparison with Java's G1 and ZGC.

• snmalloc

  8 1,489 6.3 C++

  Message passing based allocator
