difficulty of c++ compared to scripting languages is simply that there is not much high level libraries
something like qt makes c++ very simple, but its extremely large library. for examples using WebSockets in QT is no more difficult than using WebSockets in javascript. However, without QT it may be more complicated.
From c++ beginner point of view, few things can make things much easier:
- high level libraries, when everything dont need to be managed on low level. For example websocket library should automatically manage ssl.
- working build & install instructions using simple tools: make && make install should work.
- examples that work out of box with simple tools
- too much git clone, make, make install, link libraries... all this could be just made simpler. its simple when package is just apt install package, and it works by adding #include <lib.h>.
c++ is not bad language. it just is missing large dev community that builds easy to use tools and libraries. it has benefit of accessing directly hardware performance that javascript and python can only dream of.
