ReasonML has been skyrocketing in popularity lately, and for good... reason. Very recently developed by Facebook, it provides users a strong-typed, clean, and efficient syntax for JavaScript, which makes it great for web development. 

This course will get you up to speed programming in Reason. You'll start by learning how to create simple data objects and build up to more powerful tools such as functions and data structures. Along the way, interactive quizzes and exercises will help you gain a stronger grasp of the language.

Anyone looking to put themselves on the cutting-edge of web development would be well served to have a look at this course.

Functional Programming with ReasonML

## The `shape` Variant

We'll create a `shape` variant which contains the `Square`, `Circle`, and `Triangle` constructors. Each constructor will have arguments of the `float` type as its dimensions.

Whenever one of the constructors is called, the area for that shape will be calculated through the `getArea()` method.
