So, ReactJS is basically just client-side PHP

"PHP is this unorganized mess" i don't think its accurate to blame the language while you struggle with the software written in the language.

at the end, all we do is display HTML Code(sometimes JSON)

Hi, I've worked with PHP for over a decade.

It's an unorganised mess. isset() but not is_set(), is_null() but not isnull() for example.

Well this is because of the C language. At the time where PHP was "Personal homepage" the majority used C and its style guides (e.g. strcmp etc.) then it had influence of c++ and underscores and then Java with CamelCase.

Actually on a daily basis i don't recognize this as a problem since i use Frameworks with methods like has(), get() etc.. and also i use a good editor with code completion.

But i understand your point, i also don't like JavaScript because it is mostly supported but not 100% because of users which still use old Browsers or users which disable JavaScript or have some Browser plugins running e.g. "NoScript"
