Golang array vs. slice

main.go

package main

import (
	"fmt"
	"reflect"
)

func main() {

	var i = [...]uint8{0, 7, 16, 22, 28} // array, compiler counts elements
	var j = []uint8{0, 7, 16, 22, 28}    // slice

	fmt.Println(len(i), cap(i), reflect.TypeOf(i), i)
	fmt.Println(len(j), cap(j), reflect.TypeOf(j), j)
}
