Today i saw a discussion in some facebook comments if js/php are programming languages. What do you mean? Would you describe these as a programming language? Any why?

PHP is 100% one, JS is at least one too. But CSS and HTML are no programming languages!!

It depends on how you would define a Programming language.
I'd say they are kind of like script languages.

@neonoxd can you describe what is a script language? I do python, Java, golang, PHP and occasionally js. And all of them are programming languages, some compiled, some interpreted. Each as its set of strenghts and weaknesses. Usually, if I say I need to write some script, it is implied I'm using shell scripting and will be performing some automation task. And even so, shell is a programming language (although of severely restricted functionality). Both js and PHP grew a lot in terms of functionality as of late, and you can pretty much do whatever you want in it (not that I would recommend it, as described above, strenghts...). But neither is a "scripting" language (unless you meant interpreted, then you can put python, ruby and whichever other in the same stack) :)

@bolovsky i meant Interpreted languages. :D

@neonoxd well, then sir, I should tell you, you almost started a flame war :P

@bolovsky Wasn't my Intention :D and I love python so wouldn't say any is worse than the other just because one is compiled. It's just a personal "wording" :D

Both JS and PHP are Turing complete. Not that it's a great measure but just saying.

@neonoxd interpreted languages are actually compiled too right before they run.

@setyadi but you get what I mean :D

@moagggi actually, CSS3 + HTML5 is Turing complete. But CSS and HTML are no programming languages on their own.

They definitelly are.
