Basics

[]string

[]string is a slice of strings. It represents a dynamically-sized sequence of string values. The square brackets [] indicate that it is a slice, and the string indicates the type of elements in the slice.
[a b c d]

[a b c d] is an array of strings. It represents a fixed-size sequence of string values. The square brackets [ ] enclose the elements of the array, and each element is separated by a space.
map[keyType]valueType

map[string]int is a map with string keys and integer values. Maps use key-value pairs to store and retrieve data, and the keys must be unique within the map.

Loop through slice of string

  slice := []string{"a", "b", "c", "d"}

  for index, value := range slice {
    fmt.Printf("Index: %d, Value: %s\n", index, value)
  }
