If there is anything I've learned in my 10+ years as an engineer, it's that there are no good or bad languages, just pros and cons of each in different applications.
Except NodeJS. Never use JavaScript on the backend.
You're all just mad that JS stole your niche /s
I dunno if I agree really - the more languages I've learned, the more I see an evolution from less sophisticated, less usable languages to more sophisticated, more usable, modern and just generally better languages.
C and C++ are old, and you can tell. There's so much complexity and legacy in those languages that it's crazy. But it's not just legacy - it's also bad design choices. There's a lot of really bad APIs and bad usability and footguns everywhere. You see the same thing in languages like JavaScript (whose design journey has been fraught with peril). Even Java has some bad stuff I would say, mostly from the overzealous insistence on OOP.
However, if you look at some modern languages that were more deliberately designed, you really start to see how they are just intrinsically better. Python, while still being a dynamically typed scripting language which I would never use for large systems, is still leagues better than JavaScript in terms of design and usability I would say. Haskell was born from research and you can really tell - the language just makes sense in a very scientific way - although that does mean ease of use and developer experience has not always been the priority.
Rust was developed for a very particular purpose, basically to provide the same speed as C++ but without any undefined behavior. From that design principle, a lot of good has resulted and Rust is basically an objectively better language than C++. The only thing still keeping C++ in the game is the historical reasons, just due to the sheer amount of code that exists out there in C++. C++ has more support in all kinds of places, but that's just due to history and Rust will likely gain ground soon enough. For instance, C++ still rules for game development, but this could change within the next 5 or 10 years.
It's not that surprising when you think about - languages like Python, Haskell and Rust were built on the giant pile of experience the whole industry has amassed from using previous languages. It also helps that we just have more computing power today to make languages like Rust feasible. Rust compile times probably wouldn't have been realistic 30 years ago.
JavaScript is the worst, in general
i find javascript to be a great language for throwing together quick and dirty hacks.
For small programs and scripting, Node is amazing. I've even written some CLI utilities in Node as standalone executables. I think most people who bash it have either never used it, or haven't used it lately.
NodeJS has made me a very employable engineer.
Ha.
