If the tutorials aren't deliberately built up from the language's own defining philosophical fundamentals introduced singly and then in combination, then someone like me will just re-use the fundamentals I learned in whatever other languages I know that feel most similar to the new one. Most languages can be used in roughly parallel ways with just a change in syntax, even if that's not how they are supposed to be used, and if I (like most of us) have to get up and running ASAP in some new tool and don't have a quick on-ramp to establish the preferred patterns right from the start, I'll just have to re-use as much as I already know and just get on with it.
