How to assign a slice to a hashmap

I am trying to make a hash map containing keys like "cow", "bird", etc. and to each key, I want to assign a slice.

I am unable to understand how I should go about this, and even if I created it how to append to such slice.

Solution

  • I think you are looking for something like this

        animalMap := make(map[string][]string, 0)

    animalMap["cow"] = []string{"Alice", "Bob"}
    animalMap["bird"] = []string{"Tweety", "Sam"}

    fmt.Printf("%v\n", animalMap)

    // Appending value to existing slice for "cow"
    animalMap["cow"] = append(animalMap["cow"], "Chris")

    // Appending value to existing slice for "bird"
    animalMap["bird"] = append(animalMap["bird"], "Tom")

    fmt.Printf("%v\n", animalMap)
