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

## What is Polymorphism?
The meaning behind the intimidating term, "polymorphism", is really quite simple. Polymorphism refers to a certain method changing its behavior according to different situations.

This can prove very useful as the same method can be used for different purposes. ReasonML also exhibits polymorphism in some cases, and we've already been through one of them.

## Comparison Operators for Different Types
Consider a comparison operator which always gives us a boolean depending on the condition we specify. How many types can it support? We can compare *integers*, *floats*, *characters*, and even *strings*!

The operator knows the difference between these types and how to perform comparisons for each type. This is polymorphism at its finest.
