Why are there so many programming languages?
And why are there still being so many made?
I would think you would try to perfect what you have instead of making new ones all the time.
I understand you need new languages sometimes like quantumcomputing or some newer tech like that. But for pc you would think there would be some kind of universal language.
I’m learning java btw. I like programming languages. But was just wondering.
Think of a programming language as a crutch for the human brain. Processors don’t need it: they don’t have to think about the code, they just execute it. Our mushy human brains need a lot of help, however.
We need to think about things on our own terms. Different programming languages, different APIs that do the same thing, different object models, these all help people tackle new problems, or even just implement solutions in new ways.
Some new languages have a completely different model of execution you may not be familiar with. Imperative languages are what we traditionally think of, because they work most similarly to how processors execute code: the major pattern used to make progress, do work, is to create variables and assign values to them. C, COBOL, BASIC, Pascal, C# (my personal favorite), Javascript, even Rust, are all imperative languages.
But there are also functional languages, like ML or F#. (The latter, I keep installing with Visual Studio but never ever use) The main pattern there is function application. Functions themselves are first order data, and not in a hacky implementation-specific way like you’re passing machine code around. (I’ve only ever used this for grad school homework, never professionally, sadly.)
And declarative languages like Prolog helped give IBM’s Watson its legendary open question answering ability on national TV. When you need a system to be really, actually smart, not just create smart-sounding text convincingly like a generative AI, why not use a language that lets you declare fact tables? (Again, only grad school homework use for me here)
Programming is all about solving problems, and there are so many kinds of problems and so many ways to think about them. I know my own personal pile of gray mush needs all the help it can get.
