Back in 2012 I tweeted this:
Is there a c++/java dictionary? Stuff like this would make sense for teaching new languages to programmers. Languages do overlap a lot.— ruipires (@ruipires) August 2, 2012
I could have tried doing it myself, but couldn't find the time for it. This is a recurring problem of mine. I have new ideas faster than I can execute them.
It is a dictionary that shows you the similarities and differences of each language inside a "family".
Lets hope they add the ability to mix and match what languages are shown side by side.
It would be harder to implement, but might prove a lot more useful, when trying to go to a language where you can do things the same way, but that is not the best way of doing them there.
I am thinking about something like showing Python and C++ side by side. If I use Python with a C++ mindset, things can certainly work, but they will not be optimal. It would be great if this could leverage my C++ knowledge, but show me how and where to be more Pythonic. The same ideia obviously applies to other language combinations.
