I think the functional programmer guys will not be happy to
hear this.

For example, I use Mathematica, and in Mathematica, there is no
data types.  Only expressions. There are transformation
rules to transform an expression from one form to another.

A function called with an expression does transformation using
pattern rules on it. When no more rules can be applied, the resulting
expression is the function result.

But I think in the world of OO and procedural programming, what
you are saying makes sense. One defines a type, then declares
a variable of that type. i.e. data (i.e. variables) always has
a type.  But I do not think this is the case for all programming
languages?

I am now looking at JavaScript and HTML5 (to be part of the
wave of the future of software engineering), and I was
surprised to find it only has one data type for numbers. floating
points. That is it. So, one can't make an integer variable in
Javascript :)
