> When I was first learning to code ('90s), this style of "parallel arrays" was seen as a scripting-language wart.
When I first learned to program in the 80s, this was known as "Fortran order" (as opposed to Pascal or C order), and in the later nineties, I think that "column major" and "row major" became popular, and they still are.
This goes back to sometimes in the 60's, with APL and Fortran doing column major on purpose, BASIC by accident, and most of the rest doing Row major.
