100% @eightohnine - you are absolutely right to redirect us back to the core issue - accessibility to non-experts.
The reason I made this suggestion is that (1) I do care a lot about removing barriers, and (2) I have seen how those same beginners find arrays much easier in other languages.
I’d also like to redirect those interested in the technical discussion away from “square vs round brackets” back to the issue of every programmer in javascript has to “roll their own” arrays. That’s just not good in 2024.
By the way, I’m not singling out javascript. Python doesn’ have arrays - you have to use numpy.
Fortran 77 - yes, from 1977 - does have arrays. Eg real A(3,5) creates a variable A which is a 2-d array of real values with dimensions 3 by 5.
