Programming language?
Uh...
no.
It uses server scripts ,mark up languages, style sheets and scripts.
Obviously it uses HTML.
Seems to use Java Script a lot.
Doesn't seem to use any server scripts (at least not php or asp).
Uses googles services a bit.
Maybe a bit of programs on the server though, doubt it though seeing as I can't see any server scripts and it uses googles services take it's place.
@clover leaf,
If it used PHP or ASP or anything like that you wouldn't know; because you can't see PHP code in web pages after it's been parsed. Besides, I'm pretty sure it would use PHP since Javascript is client-side.
I hope so. Often, I look back upon things I've said and done in the near past, and I regret things and think "Wow, look how stupid and ignorant I was back then." It's good because it means I've learned since that time.
