This sounds to me like the journey into functional programming. I've experienced the same thing myself.

I've encountered this pretty-much every time that I've learned a new language or framework. I start out trying to use it the way I've used things before, and then I slowly learn how the people who wrote it expect me to work, and then things get a lot easier.

That too and I don't think I'm even done with that, myself :)

What I meant is the step away from the notion that things are objects, stuff gets done with methods, methods are available via mixins/ inheritance/ magic, etc.

I've seen the notion of using values and pure functions as data oriented programming recently but never understood what that moniker adds.

I think that going with pure functions/functional programming simplifies things, because it makes it much easier to test that things work as you'd expect when you don't have side-effects/state to think about.
