Programming Languages
What your software is written in, and why that outlives every framework on top of it.
The choice that outlives every framework
Frameworks come and go, but the language underneath tends to stay for the life of the system. It decides who you can hire, how the thing performs, and how much of the wider ecosystem you can lean on instead of building from scratch. Change it later and you are not refactoring, you are rewriting.
So the useful question is rarely which language is most elegant. It is which one fits the job, has the people behind it, and will still be a sensible answer in ten years. The languages below are the ones we choose from, and where each one earns its place.
