I'm a new web developer, I've learned HTML, CSS, JavaScript (jQuery including server calls with AJAX to PHP or JSON), PHP.
I can build a full website and I'm good till this point but I want to know something if you can help me.
So my question is: I see, lately, the good websites in the address bar there is no .php or .asp or .html or a get variable like (?search=query or ?id=5&some_other_get_variables), in the address bar of these sites I find like folder slash (domainname.com/search/query).
I just want to know what kind of web development is this.
