在Go中附加二维切片

Question

I have a couple 2 dimensional slices in my Go program and I want to join them together.

However, append() doesn't take this type.

cannot use myArray (type [][]string) as type []string in append

How do you append multi-dimensional slices using Go in an idiomatic way?

Answer 1

Use ... to pass the second slice as variadic parameters to append. For example:

a := [][]string{{"a", "b"}, {"c", "d"}}
b := [][]string{{"1", "2"}, {"3", "4"}}
a = append(a, b...)
