What would your language of choice have been? And why is java horrible for this scenario? it sounds like a reasonably good choice to me
I’m thinking Go or Rust would be the logical next step. They probably won’t want an interpreted language so Python is out.
Just curious, what about go or rust makes them the logical next choice and not java? What do go or rust do better that java doesn't?
Java is an Oracle honey pot, a royal sustainment PIA, massive security liability, clutters up systems with its nonsense and slow as shit.
“dear diary, despite running on a system with 1TB of RAM, a routine security patch reset the Java max memory quota and now every Java process stops after 256MB of object allocation. All four threads ran out of memory with 999GB RAM free. Thank you for this wonderful and blessed gift of computational ineptitude, amen.”
Rust - absolutely.
If they don't want interpreted Java is out too
javascript
JavaScript is worse than COBOL.
I’m assuming there is an implied /s here
JavaScript is actually really nice as a beginner programming language because of how quickly and visually you can see your results, and how easily you can debug with console output. Yeah it's horribly unoptimized but it's not for big things. It's for little things. It's baby's first programming language.
It actually is pretty quick. Dont sleep on JavaScript capabilities. However, it is untyped. You wouldn’t want the date you wrote your check to become the amount of your check, for example.
TypeScript does a nice job there but all in all at that point might as well go all in on a typed language.
Python, anyone?
Not nearly as performant as either Java or COBOL.
What
Java is a POS and mainframes run faster emulated on a rasberry pi vs the actual hw.
The real answer is you want a typed language with financial transactions. But even python would be better than Java.
