F# Unit Type

The unit type is a type that indicates the absence of specific value. The unit type has only a single value which acts as a placeholder when no other value exists.

 let function1 x y = x + y                 function1 10 20      // this line results a compiler warning      // changing the code to the following, eliminates the warning let result = function1 10 20  // Use this if you are calling the function and don’t want the return value function1 10 20 |> ignore
