I mean I’m a C++ programmer too, but I learn other tech so i dont end up myopic in how to best solve a problem. You shouldn’t learn node.js because its “new” (also: its definitely not new anymore), you should learn node because c++ is bad at most of the things node is good at (and vice versa). (and before you think im picking on systems programmers, I also have a dim view of web developers that refuse to learn any non-web tools)
