Having worked extensively in Java, Node, and Python, I’ll take the JVM ecosystem absolutely any day of the week.

Me and my catheter will be over here delivering actual software while you figure out how React 32 broke your transcompiler.

No idea why you are comparing Java, which is BE, to React, which is FE.

I think I will check Java once they finally make coroutines… I mean “virtual threads” a stable feature. That actually looks exciting… being able to parallelize almost like in Go 5 years ago.

Don't you mean fibers? Anyway, I'm pretty sure it's targeted to JDK21.

Fibers are now called virtual threads

Except I’m over here serving 10x the traffic with 10x less cloud spend on CPU and Memory for hosts.

In what language would that marvel be? I give you the less memory....

Go has goroutines which have better cpu and memory than threads which are commonly used in java.

Java is now catching up with go and adding virtual threads which in september 2023 will have the same ease of use as go had in … 2007?

But as I wrote above, it migh really get me to check java again.

Well is it correct that until 1.14 (so 2020) Go used cooperative scheduling? Because Java Threads, (before the new virtual threads) are preempted by the OS...Go was launched in 2009? Who is doing the catching up?

Maybe you should upgrade from Java 1.4...

Say that to enterprise software systems still running on Java 7 or 8 without any clear path to upgrade because their whole systems will break.

It’s almost like there is even a CS law for this exact scenario.. but Java 8 will be around and will still work 10 years from now, plus it is not an insurmountable task to bump it up to the latest version at all. Tell me literally any platform that has a better backwards compatibility story, because honest to God there is simply absolutely none.

Java 8 will be out of support in 7 years. It might seem like a lot but for enterprise systems it's nothing.

Which gives you a lifetime support of 16 years for a single version, with an absolutely sane and doable upgrade path.

C++. And it’s hated for the same reasons.
