Sometimes these ideas influence the entire industry. See these StackOverflow questions for more info: 1, 2.Įsoteric languages like those included in this collection, are a way to propose and validate new ideas. There is an entire website dedicated to JavaScript's weirdness, but to give you an example, here are two small JS snippets that are perfectly valid (you can try them out in your console): // This prints 10:Īlert((!+)]+(!+)]+(]+])+]]+(!+)+!+]) The side effect of this is that every idiosyncrasy of the language, however subtle it is, causes bugs in the code of thousands of programmers every day, which earns JS a place on this list. JavaScript is the most popular programming language today. You might also be interested in Shakespeare. Here is an example program: Display 'Hello world!' and a newline. No functions can be defined by the programmer - he may only use the built-in ones. Its syntax is very loose to give the writer a greater freedom of expression. ~English is a programming language that attempts to imitate natural sounding language. Here is an example of a program that outputs a Fibonacci sequence: |z2Vxwv-,POqponl$Hjig% more here. According to the author no other language is implemented like this, because it would be idiotic. It combines an unintuitive postfix notation with heavy object-orientation, requiring extensive juggling of a main stack combined with its object-oriented structure. Glass is an esoteric programming language developed by Gregor Richards in 2005. If you need a more powerful version, check out LOLPython, which is inspired by LOLCODE and gives you access to all of Python's powerful libraries.įor more code and examples, see this Wikipedia entry. This means that you won't be able to use LOLCODE for anything more than reading a file or writing text to the console. You can almost imagine a cat using it in production! HAIĪs with most of the languages in this list, there is no standard library to speak of. The keywords of the language are all capitalized and meme-fied. It was created in 2007 by Adam Lindsay, researcher at Lancaster University. 1) LOLCODEįew programming languages are infused with the internet age as much as LOLCODE. Here are 10 of the most weird and impractical ever created. Sometimes programming language designers create a language that goes against these principles, either as research or for fun. Their syntax should be clear and understandable, and their implementations bug-free and fast.

They should give you structure and allow you to solve real problems. Programming languages are supposed to be easy to use and learn.
