Programming Language
Programming language is an artificial language created for humans to communicate algorithms to computers easily. Such language often tries to mimic human language (practically always English) but is much MUCH simpler so that a computer can actually analyze it and understand it precisely so it also partially looks like math expressions.
For noobs: a programming language is actually much easier to learn than a foreign natural foreign language, it will typically have < 100 words to learn (out of which you'll mostly use like 10) and once you know one programming language, learning another becomes a breeze because they're all pretty similar in basic concepts. The hard part may be learning some of the concepts.
A programming language is distinct from a general computer language by its purpose to express algorithms and be used for creation of programs. There are computer languages that are NOT programming languages (at least in the narrower sense), such as HTML, json and so on.
We divide programming languages into different groups. Perhaps the most common divisions is to two groups:
- compiled languages: Meant to be transformed by a compiler to a native (directly executable) binary program. These languages are more efficient but usually more difficult to program in, less flexible and the compiled programs are non-portable (can't just be copy-pasted to another computer with different architecture and expected to run). These languages are usually lower level, use static and strong typing and manual memory management. Examples: C, C++, go, rust, Haskell or Pascal.
- interpreted languages: Meant to be interpreted by an interpreter "on-the-go". Basically to run the program you need the interpreter of the language installed on your computer and this interpreter reads the source code as it is written and performs what it dictates. These languages are generally less efficient (slower, use more RAM) but also more flexible, easier to program in and independent of platforms. These languages usually higher-level, use weak and dynamic typing and automatic memory management (garbage collection). Examples: Python, Perl, JavaScript and BASH.
Sometimes the distinction here may not be completely clear, for example Python is normally considered an interpreted language but it can also be compiled into bytecode. Java is considered more of a compiled language but it doesn't compile to native code (it compiles to bytecode).
We can divide language in many more ways, for example based on their paradigm (impertaive, declarative, object-oriented, functional, logical, ...), purpose (general purpose, special purpose), computational strength (turing complete or weaker), level of abstraction (high, low), typing (strong, weak, dynamic, static) or function evaluation (strict, lazy).
Nice Languages
THIS IS NOT A COMPREHENSIVE LIST, I can only include languages that I am familiar with, please add more ~drummyfish
- C: the one and only, the go-to language of the suckless community and of compiled languages in general, greatly future-proof, uncontested in performance and with nice oldschool meme-free design, our beloved C
- Forth: beautifully simple stack-based language
- Lambda calculus: ultra extremely minimal mathematical functional language
- Sigma calculus: yes or no? seems like yes
- Brainfuck: However funny and meme this language may look, its simple design is actually pretty beautiful and interpreters are ultra extremely simple to make.
