How to make a native chat app in Swift?

Why didn't Facebook choose Node.js or Go over C++ when moving away from Erlang for its chat app? Is there any way to make C/C++ concurrent?

  • Answer:

    has a good answer here: He says that Facebook had more experience and more internal libraries in C++ and thus C++ was a logical choice. But read his whole answer for some good context. As for making C++ concurrent, I'm not sure what you mean. There are no language primitives for concurrency, but it's pretty easy to write concurrent classes by using the appropriate threading and locking mechanisms provided by the OS. There are also tons of libraries for writing concurrent code in C++.

Ditto , there are lots of ways to do concurrency in C/C++ (see: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CCoQFjAB&url=http%3A%2F%2Fwww.tutorialspoint.com%2Fcplusplus%2Fcpp_multithreading.htm&ei=eYqPVKqeDc21oQSbx4LIDQ&usg=AFQjCNFZ2JWMY-hZS2kG_vIy3XUqK4aQ6Q&sig2=z-fNgEb2XxCo21vSbOXMTw&bvm=bv.82001339%2Cd.cGU).   It's just trickier to do so than in Erlang, where more is built in to the language and there aren't troublesome side-effects. Available ecosystem and programming talent trumps abstract advantages many days of the week.
