Haskell Type vs Data Constructor
I am learning Haskell from learnyouahaskell.com . I am having trouble understanding type constructors and data constructors. For example, I don't really understand the difference between this:

Git search for string in a single file's history

How to print the values of slices
...

a := []string{"[a]", "[b]"}
fmt.Print(strings.Trim(fmt.Sprint(a), "[]")
