F# 101

This is a series of hands-on examples that will teach you the basics of F#.

You should read the script files present in this repository in-order.

Prerequisites

1. Make sure that you have a F# environment installed. You can install F# on Mac, Linux and Windows.
2. Recommended for beginners: Install Visual Studio Code and the Ionide plugin for enabling F# development within VS Code.

You should be able to create a new F# script file in your editor, and evaluate it. In VS Code, this means creating a new .fsx file, and evaluating expressions by selecting them and pressing Alt-Enter.
