Learning Functional Programming in Go

Map Example

Here's an example of mapping a collection using the alediaferia/go-collections package:

names := []interface{}{   "Alice",   "Bob",   "Cindy", } collection := collections.NewFromSlice(names) collection = collection.Map(func(v interface{}) interface{} {   return strings.Join([]string{"Hey", v.(string)}, " ") }) println(collection) // or the use of fmt.Println(collection)

The output is as follows:

Hey AliceHey BobHey Cindy
