This is something I'll never understand: Isn't the only selling point of JS that it runs on every web browser? Why would anyone want to use it (or, in 2021, PHP) on the server side, where you can use any language you want?
Hah, I've been saying the same thing for years. It bothered me even more so because I was a Perl programmer and everyone kept saying how messy Perl code is. But they want JS on the backend?!
