A Tour of Go Arrays

The type [n]T is an array of n values of type T.

The expression

var a [10]int

declares a variable a as an array of ten integers.

An array‘s length is part of its type, so arrays cannot be resized. This seems limiting, but don‘t worry; Go provides a convenient way of working with arrays.

package main 

import "fmt"

func main() {
    var a [2]string
    a[0] = "Hello"
    a[1] = "World"
    fmt.Println(a[0], a[1])
    fmt.Println(a)
}
