I have a question, especially for those who’ve been programming for some time or have experience with older languages:

What improvements have you seen in programming languages that aren’t related to syntax or semantics of the language?

I’m thinking about things like the introduction of package managers for pulling in third party dependencies, and the existence of code formatters or linters.

I guess integrated testing into the tooling / language in rust and golang would count as well.

( Another way to frame this would be what do you miss when you are programming in c or c++ or some older language that isn’t the language, but more about the tooling and ecosystem.)
