Why can't GO just have arrays. Why do I have to learn new things like slices :(

    Go has arrays.
    Slices are like arrays as well, they are just dynamically sized. Slices are just extended arrays

    @byte are go slices similar to C++ vectors?

    @Zennoe do you mean if internally it is just a pointer, a current size and a capacity (c++ vector)? I guess slices don't have the capacity. Usually they are readonly in respect to pushing more items.

    @Zennoe kind of same from wht I've read ( I don't have much experience there )

    @anicka-burova slices have a capacity as well as length.
    Slices are like references to arrays

    learning go wait till interface skull fucks your brain ...
    this implement that implement those so you could....

    anyway when you wrap your head round its the best language ever

    @byte array slices is a subset extract from an array. Slices intention is a view in to the array. Capacity has no meaning here.

    @anicka-burova slices can be an independent entity
    They are Go's way of implementing dynamic arrays
    sl := make( [ ] int, 0, 5)
    Makes a slice of length 0 and capacity 5
    s := make( [ ] int, 5)
    Makes a slice of length 5 and capacity 5

    @byte I admit I never done Go. Slice is a technical term in programming, which looks like might be used wrong in Go.

    In c++ vector is an implementation for dynamic sized array. Calling it vector might be a bad idea as well.

    In pseudo programming, if somebody would use SLICE word, I would understand it as a view in to a subset of an array. There you wouldn't need a capacity obviously.

    Sorry for misunderstanding.

    @anicka-burova Go slice is a little different than the traditional SLICE

    Yeah, I can see why they'd be misunderstood

    It takes time to get your head around these things in Go, but once you do its a great language

    @byte my hobby is trying new languages, one day...
