F# Function Composition

In F#, functions can be composed from other functions. It is a process of composing in which a function represents the application of two composed functions.

The composition operator (>>) takes two functions as operands and it returns a function.

F# Function Composition Example

 let function1 name=    name + ” FSharp” let function2 name =     name + ” Programming”  let programmingName = function1 >> function2 let result = programmingName “Hello” printf “%s” result 

Output:

Hello FSharp Programming

F# Function Pipelining

F# function pipelining allows us to call functions in chain. Pipelining operator takes a function and an argument as operands and returns a value.

F# Function Pipelining example

 let function1 name=    name + ” FSharp” let function2 name =     name + ” Programming”  let result = “Hello” |> function1 |> function2 printf “%s” result 

Output:

Hello FSharp Programming
