Difference between `type foo struct` and `type foo []struct`

What is the main difference between these structs?

type foo struct {
    Name string `json:"name"`
}

and

type foo []struct {
    Name string `json:"name"`
}

The first is a struct type which is named. It can be initialized in the usual way:

// Initialize a foo
f1 := foo{"name1"}
// Initialize a foo slice
f1s := []foo {
  foo{"name2"},
  foo{"name3"},
}

The second is a named slice type whose elements are anonymous structs with the given fields. It can be initialized like this:

f2 := foo {
  {"name4"},
  {"name5"},
}

type foo1 struct {
    Name string `json:"name"`
}

type foo2 []struct {
    Name string `json:"name"`
}

Simple understand as

type foo2 []foo1
