Well. You’d have to demonstrate that a[1] is the first offset in an array, and it’s not a great curb appeal to anyone who has programmed computers before.

It makes sense when you look at how the numberic for loop looks in Lua.

In Lua you specify the “beginning” and “end” of the iteration, both included. It doesn’t work like in C, where you have an initialization and an invariant. What makes it short in C would make it longer in Lua, and viceversa.

You could argue “why not make loops like C”, then. But that can be extended to the limit: “why have a different language at all?”.

i think i might prefer indexing starting at zero, but it really isn't important. with c it makes total sense for zero-based indexing. frankly though, for lua, how it works and what an array is, it makes more sense for one-based indexing, the only counter-argument being that 1-based indexing puts off people who learned a thing one way and are unable or unwilling to do it a different way. to even include it on a list of considerations for not choosing lua is a bit silly, but to highlight array indexing and only that as the only thing you'd need to know... well i don't know how to put it that wouldn't be impolite.

either way, at least you can't toggle between indexes starting at zero and one, (at least not that i can recall.)

I don’t see a problem. That’s how people count.
