It does some things at scale very well and has been afforded the performance improvements of very smart people for 30y.
Itโs not to say the language isnโt verbose, one of my favourite features was the ability to write code in other languages right inside the a Java app pretty well in-line by using the JVM, thanks to JSR-223.
