I was intrigued to learn more about the winning language Nim to see how it beats C/C++, so I did a web search and was confounded to see Nim compiles to C/C++! What gives? Starting to doubt the methodology somewhat, though it was an interesting read.

Probably more about the difference between "echo" and "std::cout << ... << std::endl;" than the recursive function call.

  I would be very very surprised if printing "2971215073" accounted for more than 1 second of runtime.

    Well, I know that printing stuff to console can be ridiculously slow, so this doesn't surprise me much.
    - Sean1708 8y ago
      An entire second to print 10 characters?! How does a terminal that slow even exist?

  Most of it won't be because the C++ constexpr version has the same IO call and runs in <0.1s.

    I think that's because even the std::cout call could be precalculated, so no runtime string concatenation and stream magic is involved.

  std::endl flushes which isn't cheap, you're generally better off simply steaming in a newline.
