OffsetArrays.jl

I always like to point to the Julia package TwoBasedIndexing (https://github.com/simonster/TwoBasedIndexing.jl/) which is IMHO provides the very best way to index an array. Yes, Julia defaults to 1-based indexing, and allows zero-based indexing (https://github.com/JuliaArrays/OffsetArrays.jl) or indeed whatever sort of indexing you want, yet I think the world is going to eventually come around to THE ONE TRUE indexing scheme of being two-based. :-)

You can use whatever start index you like: https://docs.julialang.org/en/stable/devdocs/offset-arrays/#... For a pre-baked solution: https://github.com/JuliaArrays/OffsetArrays.jl

If you feel uncomfortable, note that Julia internally has some indirection to allow for custom offsets. See for instance OffsetArrays.jl [1] [1] https://github.com/JuliaArrays/OffsetArrays.jl

I know it is not the default, but this package has no overhead over the default arrays according to recent benchmarks, and provides 0-indexed arrays: https://github.com/JuliaArrays/OffsetArrays.jl I confess, not being the default is a big thing. I've definitely had times where I thought "this would be easier with 0 indexed arrays", but it can then be harder to commit to adding a dependency and making that change vs just adding awkward looking "+1"s to all the indexes. Coming from math/science, there's lots of times 1-indexing makes more sense / is more familiar. It's normal there to start counting from 1, so it can be easier to translate.
