Emacs Lisp, and other popular Lisps as well, are multi-paradigm
languages. They support many paradigms but do not force any of them. For
example, imperative and functional programming is supported. It's a
common myth that Lisps are (purely) functional languages. They are not.
In my experience the first big difference for a Lisp newbie is that
there are no separate statements and expressions; there are only
expressions. Another thing to realize is that Lisp code is actually Lisp
data (trees of cons cells).
