I'm surprised to see Javascript in decline since 2017. Most of that can be explained by substitution to Typescript but it's still down a couple percent with that factored in.

Based on the graphs here, Go and Python are also stagnant/slightly declining. Rust seems to be stagnant too since 2022.

The best I can make from the graph is that those declines are a scaling adjustment for a recent meteoric Java growth.

(WTF is there a meteoric Java growth is yet to be explained.)

Recent releases of Java have dragged the language kicking and screaming into the late '70s, and so people are starting to appreciate how much the JVM ecosystem gets right (instrumentation, dependency management, IDEs etc.).

Either that or the institutional memory of Java EE has faded, and Spring Boot is here to traumatise a new generation of developers with the magic of write-only COME FROM code.

To keep it in perspective, we are talking about a single month, and it wasn't enough to go back to the share it had half a decade ago.

Those things you cited do no cause single-month rapid growth. What causes it is publicity, or some large ecosystem adopting it by fiat.

So the grandparent is not even close.

In most metrics there it's steadily rising even, though the metrics are cross-correlated with "GitHub adoption".

If you sort by Issues, C++ is #3 and trending up.

Sounds about right! :D

That just seems to show proportions on github - it may be with the growth in the total sector size the absolute number is still increasing.

But yeah a 0.234% yoy-decrease isn't "plummeting". If so, then things like typescript or python are even steeper in their, and java being the next big thing showing massive growth compared. And rust itself is decreasing according to those stats, so I guess it's declining too.
