F# Example

F# is a functional programming language that offers a concise and expressive syntax. In this page, we will explore a basic example of F# to understand its syntax and usage.

Syntax

let functionName arg1 arg2 =
    // Function body
    // Code to be executed

Example

Let's write an F# function to find the sum of two numbers:

let sum a b =
    a + b

Output

If you call the above function with arguments 2 and 3, you will get the output as 5.

sum 2 3
// Output: 5

Explanation

The let keyword is used to define a function with its name and arguments. In this example, we have defined a function named sum that takes two arguments a and b. We have defined the function body followed by the code to be executed inside it. In the function body, we have added the value of arguments a and b and returned the result.

Use

Functions are the building blocks of F# programming. It is used to perform specific tasks and return values. With F#, you can write highly modular and maintainable code using functions.

Important Points

• F# is a functional programming language that offers a simple and easy-to-use syntax.
• let keyword is used to define functions in F#.
• F# emphasizes on immutability and purity of functions.

Summary

In this F# example, we have learned how to write a basic function to find the sum of two numbers. We have also covered the syntax, output, explanation, use, and important points of F# programming. F# offers a robust set of functions and libraries that can help you write efficient and effective code.
