Arrays

Initialize array to 0 values

a := [3]int{}
fmt.Println(a)

[0 0 0]

Set to width of provided literal

b := [...]int{5 + 5, 20, 30}
fmt.Println(b)

[10 20 30]

Compare arrays

// Arrays can be compared in go, but Slices cannot
println(a == b)

false

Set by index, blank are initialized to 0

d := [6]int{1, 2: 4, 5, 5: 100}
fmt.Println(d)

[1 0 4 5 0 100]

Multidimensional array

e := [2][4]int{}
fmt.Println(e)

[[0 0 0 0] [0 0 0 0]]

Go has a simple multidimensional array implementation which incurs performance penalities
