Markup languages simply describe the layout and organization of a user interface and is largely static. You cannot describe behavior of a program with it because it contains no operators for logic, control flow, etc.



Compilation isn't really a requisite for being a programming language. There are purely interpreted languages, byte-code compiled (this gets complicated sometimes) and purely compiled languages.

Wow thanks for the info

I just recently started codeacademy myself. I'm done with most of the HTML and have just started a bit of CSS. I enjoy that I can go at my own pace and continually progress. If anything I want to learn enough of the basics so that when I'm talking to someone about a web development idea I can at least somewhat understand what is possible and be able to communicate with an expert more efficiently. Hopefully over a few years I'll learn enough to work on my own ideas myself. I just hope the languages dont get outdated by the time I learn them (not sure if its even a realistic worry).
