Functional programming

[nionita]

You do not do assignments, you just name values. Like in mathematic.

But for a hash table you have the IO monad, where you can do what you want.

Still, the model is harder to implement in a mutable world (like the processors are), so the program is slower (see Barbarossa).

Better only write small minimal programs. For they are saying object oriented programming is no good, Functional programming is no good. Test driven development is dead and behavior driven development is bad.

And who knows what they make you believe in the future.

By the way also inheritance makes no sense. For instance a circle is not a shape because rotating a circle makes no sense.

And a square is not a rectangle for having both width and height is redundant.
