Sorry, I think React was not Client-side framework, it's only "A JAVASCRIPT LIBRARY FOR BUILDING USER INTERFACES" (taken from it's website). As we know, it's like jQuery, few people call it "Javascript Framework", but it's only "Javascript Library". CMIIW, thanks before :))

I don't think rails is the most popular worldwide. Almost certainly that is PHP. Perhaps in your circles rails is popular. I know view few rails programmers myself.

PHP isn't a framework though.

It more or less is. It's a language and a web framework. That happens to have other frameworks built on it.

Sorry for late reply but I am genuinely curious on how you think PHP is a web framework? At best you can say it has routing built in, but no one even uses just php files as they are for "routing" anymore. How else is it a web framework? Especially over other scripting languages like Ruby that have a strong focus on web dev, but are just languages?

No actually you don't what a programming language is! PHP is a web programming language ( Not a General purpose one though ) which is completely a different stuff from a framework. Laravel is a framework written in PHP. Like the fucking Django framework which you can't think of any other modern technology. I loathe dinos who just stick to an old programming language ( like C )

Would be surprised if React was more popular than Angular 1.x, but it definitely has more traction than both 1.x and 2.
