Julia also has 1-based indexing .. You get used to it pretty quickly.
You don't if you're writing low level algorithms. It's difficult for me to articulate the exact problem but I liked 1-based indexing until I needed to implement some algorithms that operated on multi-dimensional arrays element wise. Things just don't compose the right way.
It's actually the primary reason I don't make more use of Julia. I like the syntax and overall design more than Python but it just isn't worth it to me.
(If you're wondering what I'm doing in an Lua comments section, it's because I really like the ideas behind some of the Lua based languages such as Terra.)
One or zero indexing is a question about domain and communication. In signal processing, it is quite normal to need a negative index (autocorrelations f.x.). Ada (and I believe Pascal and Julia) has supported for specifying the indexing type, which can then be selected to match the problem domain.
In LUA you can use the metatable functionality to implement 0 based indexes.
In Julia you can overload the array access operation too. There a packages which allow zero based indexing. Or even StarWars based indexing including the machete viewing order. https://github.com/giordano/StarWarsArrays.jl Julia's array interface has has functionality what the first/last index is, so you can use it in other peoples code. If they haer coded 1 as first index just make a pull request to fix it.
I tried to do that a while back and kept coming across corner cases that didn’t work. Is there a complete implementation of zero-based arrays for Lua available anywhere?
Maybe you should try it before passing judgement.
I moved from Matlab to Python and the biggest improvement was zero-based indexes.
Apparently this little detail is never taken into account.
