Append []byte arrays

[ThePiachu]

I recently tried appending two byte arrays in Go and came across some
odd error. My code is:

one:=make([]byte, 2)
two:=make([]byte, 2)
one[0]=0x00
one[1]=0x01
two[0]=0x02
two[1]=0x03

log.Printf("%X", append(one[:], two[:]))

three:=[]byte{0, 1}
four:=[]byte{2, 3}

five:=append(three, four)

And the errors are:

cannot use four (type []uint8) as type uint8 in append
cannot use two[:] (type []uint8) as type uint8 in append

Which taken into consideration the alleged robustness of Go's slices
should't be a problem:

What am I doing wrong, and how should I go about appending two byte
arrays?

one = append(one, two...)
the signature of append is, for any fixed T, append([]T, ...T)

Append adds elements to a slice of elements. You're trying to append a slice to a slice. You can do this by using ... ("dot dot dot").

var s []int{1, 2}

var t []int{3, 4}

s = append(s, t...)

// s == []int{1, 2, 3, 4}
