I've compiled a small reference about programming languages and what they are used for.
Just save it in your bookmarks for future reference ;-)
1. Clojure: A modern Lisp dialect for the JVM. Used for functional programming, concurrent programming, and building scalable systems.
2. Haskell: A purely functional language with strong static typing. Often used in academia and for complex algorithms.
3. Kotlin: A statically typed language for the JVM and Android. Known for its conciseness and interoperability with Java.
4. QBasic: An introductory programming language. Used for simple games and educational purposes.
5. Forth: A stack-based, procedural language. Used in embedded systems and for low-level programming.
6. LOLCODE: A humorous, esoteric programming language. Not used for practical purposes; more of a novelty.
7. BrainF: Another esoteric language known for its minimalistic design. Mostly a novelty or for challenge.
8. Emoticon: An esoteric language using emojis. Mainly for fun and not practical applications.
9. Bloop: A theoretical language designed for an educational context, to explain computability.
10. Unlambda: An esoteric functional programming language. Used for exploring functional programming concepts.
11. CoffeeScript: A language that transcompiles to JavaScript. Used for web development, offering more readable syntax.

13. APL: Known for its array programming capabilities. Used in scientific, financial, and engineering fields.
14. Lua: A lightweight scripting language. Used in game development and embedded systems.
15. Ruby: Known for its elegant syntax. Used in web development, especially with the Ruby on Rails framework.
16. Roy: A small functional language that compiles to JavaScript. Used for experimenting with functional concepts in web development.
17. Python: A versatile language known for readability. Used in web development, data science, AI, and more.
18. Node.js: Not a language, but a JavaScript runtime. Used for server-side web development.
19. JavaScript: Essential for web development, both client-side and server-side with Node.js.
20. Deno (beta): A secure runtime for JavaScript and TypeScript. Used for server-side development.
21. Golang: A statically typed language by Google. Known for concurrency, used in cloud and network services.
22. C++: A powerful language for system/software development. Used in game development, software, and embedded systems.
23. C: A foundational language for system programming. Used in operating systems, embedded systems.
24. C#: A language for Microsoft platforms. Used in enterprise software, game development with Unity.
25. F#: A functional-first language on .NET. Used for data science, enterprise software.
26. HTML, CSS, JS: Essential trio for web development. HTML for structure, CSS for style, and JS for interactivity.
27. Rust: Known for memory safety. Used in systems programming, web assembly.
28. Swift: For Apple ecosystems. Used in iOS and MacOS app development.
29. Python (with Turtle): Python used for educational purposes and simple graphics.
30. Basic (beta): An easy-to-learn language. Used for education and simple programming tasks.
31. R: For statistical computing and graphics. Used in data analysis, statistics.
32. Bash: A Unix shell and scripting language. Used for automating tasks in Unix systems.
33. Crystal: A language with Ruby-like syntax and C-like performance. Used for web and general-purpose programming.
34. Julia: For high-performance scientific computing. Used in data science, machine learning.
35. Elixir: A functional language for scalable applications. Used in web development, especially with Phoenix framework.
36. Nim: A systems and application language. Known for efficiency and readability.
37. Dart: Designed for UI development, especially with Flutter for mobile apps.
38. Reason Node.js: A syntax extension for OCaml, used with Node.js for JavaScript-like development with functional features.
39. Tcl: A scripting language for embedded systems, testing, prototyping.
40. Erlang: For scalable, concurrent systems. Used in telecoms, messaging systems.
41. TypeScript: A superset of JavaScript. Adds static types, used in large-scale web development.
42. Pygame: A set of Python modules for game development.
43. Love2D: A framework for 2D games in Lua.
44. Emacs Lisp (Elisp): For extending the Emacs text editor.
45. PHP Web Server: Used for server-side web development.
46. SQLite: An embedded database engine, not a language.
