Programming languages & proof of concepts

Question

There are plenty of programming languages out there, as you all may know. I am primarily looking for a list of programming languages WITH some very neat proof of concepts. I would really like to learn a new language, but whenever I dive into something new and popular, it isn't what I expected. Any tutorial out there will give you code, small examples, but won't show you the true power of the language. I am looking for examples that run entirely on the language that it is exemplifying.

For example, If I said C#, I could possibly show you a complete C# app with backend queries, reports, tables, all with a nice interface. The end program/app would be completely reliant on the language that is provided, so no side-by-side languages. I understand that most languages are integrated with other languages in order to provide a richer application.

Any links, charts, websites that may reflect this request is appreciated.

Answer 1

If by proof of concept you mean a piece of software that does something non trivial, then I would suggest looking at popular open source projects written in your language of choice.

Sometimes you can find sample software - this is particularly true for microsoft. An example for C# would be the Nerd Dinner sample.

Answer 2

Not sure what you are looking for, but it makes me think of the "battery included" conception guideline of python.

Except for very limited specialized language "what a language can ultimately do" is meaningless, all turing complete languages are equivalent at some level, provided you have minimal necessary IO. Usually languages do nothing by themselves, they come with a more or less complete or useful set of libraries and tools appropriate for some problems. But that is not a language problem, more of an ecosystem one.

Answer 3

If you want to learn a language that doesn't use any other languages, try writing something in assembly or machine code!
