For the everyday developer messing with data, there are some nice concepts to know.

I'm talking super basic like when is it useful to transpose a dataset, to apply some function, then transpose back?

Being congnizant of the data-shape is something that comes as a side effect of studying linalg and matrices.

Just recognizing things like that will be the most value add unless you get into some domain specific requirements (games/engineering software).
