Please ELI5, I lost track. I used to learn a bit of C and a bit of Python a few years ago but never really went deeper into programming. And now suddenly it seems that a host of new programming languages have appeared and that stuff that used to work fine in whatever old language it was in is now rewritten in a new language.
How do languages like Golang and Rust differ from older languages (these two have probably been around a while but for me they feel ‘new’)? Why are we coming up with new languages all the time? Besides those two, what other languages are there worth knowing about? Is it worth learning them? Are they going to come up with yet another one next week? (I know, many questions, an invitation to infodump I guess …)
Take a look at LISP, Prolog and Erlang you’ll be able to answer the question yourself. Just a little tutorial for each of them. You’ll notice they have very different but fascinating ideas about how things could or should be done.
Maybe after a while you’ll get thoughts like “I wish language A had this feature of language B” and that’s kind of how new languages appear. Because it’s often not possible to add such features or concepts to established “old” languages without breaking everything or losing backwards compatibility.
