如何在Go / Golang中使用map [string] string或自定义结构？ [关闭]

While reading some open source, I found the following code:

type Values map[string]string

But also:

type Value struct {
    key string
    value string
}
type Values []Value

So, are those two different? Thanks!

The maps are unordered, slices retains the order of insertion.
