Very few? There's plenty of apps out there written in PHP. You can do the same thing in PHP as you can in node. Writing from scratch is no greater of a use case for using node than it is for PHP.
Yes, there are. I didn't say there weren't. I think PHP is great, relax.
In my professional experience, however, I don't see people start a codebase from scratch in PHP anymore. It's almost always based on Node.
Err.. that's exactly what you said, no?
Well, yeah, if you work in a shop where node is the goto solution on the server side, that's going to be your experience.
