Answer 2

There are interesting lectures on functional programming by Dmitry Soshnikov (but mostly in F#).
Let's say you see x = 2+3.
We can say: calculate the expression and put the result in cell x.
And a functional programmer will say: you have described (calculation method) function x (that is, you have not commands, but a function definition). From a bunch of definitions, the compiler will try to find a shortened version that will be the solution when substituting data.
