Call it "Go", for example.

I present to you "Gangam C"
I'd imagine these days typescript or node might be taking over some of what would have hit on javascript.
But there is likely some decline for Java. I'd bet Elixir and Erlang have been nibbling away on the JVM space for quite some time, they make it pretty comfortable to build the kind of systems you'd otherwise use a JVM-JMS-Wildfly/JBoss rig for. Oracle doesn't help, they take zero issue with being widely perceived as nasty and it takes a bit of courage and knowledge to manage to avoid getting a call from them at your inconvenience.
Which is a pity, once you learn to submit to and tolerate Maven it's generally a very productive and for the most part convenient language and 'ecosystem'. It's like Debian, even if you fuck up badly there is likely a documented way to fix it. And there are good libraries for pretty much anything one could want to do.
b) The ultimate hard search topic for is 'R' / 'R language'. Check if you think you index it corectly. Or related terms like RStudio, Posit, [R]Shiny, tidyverse, data.table, Hadleyverse...
