Learning F# Functional Data Structures and Algorithms

The Hello World example

No book is complete without some quintessential Hello World examples. So here it is:

printfn "Hello World";;

Yes, this is all you need. Notice the terseness, simplicity, and lack of clutter. Now let's run this in the F# interactive environment. In order to run it, you would need to have ";;" at the end of the statement. We will provide more details on this interactive environment setup later in Chapter 2, Now Lazily Get Over It, Again.

This is the response that you see when you run the preceding line of code. It is a minimal viable example; however these attributes of simplicity, terseness, and simplification extend beyond HelloWorld ...
