How to handle indexing into empty arrays in non verbose way

[reef pendant]

My issue is that I have a struct that's has bunch of arrays that can be empty. Some of this arrays hold other arrays
I want to access data in this arrays but not error when they are empty. So my issue is that i can't figure out way to do that in non verbose way which would suck to write

arrays can't be empty, you can access them without checking for errors.

they can have 0 items that what I'm talking about

I think he means slices

There's no way to check without an if somewhere, whether you want to make a helper function that checks the length for you is up to you

at this point i might just implement Vec and Option

I don't know what those are

does vec not panic?

[reef pendant]

Vec has methods that return option and Option has method to return default at None

wait wrong code

I would advise you to try and break the habit of calling slices arrays, they're not the same thing.
I understand that using concepts from other languages seems easier but if they set root they'll be hard to get rid of

(re: deleted code)

func ReturnFirstOrDef[T any](arr []T) T {
    var t T
    if len(arr) == 0 {
        return t
    }
    return arr[0]
}

here is the code

didn't even know its an issue

will remember that

not calling things by their proper name is almost always an issue
this is one example of why the distinction matters #1138410843302789210 message

it's fine to use crutches, you just need to be aware of that so that they don't bite you in the future

ya sould figure it out sooner silces don't have methods any fancy methods on them
