Explore ReasonML's growing popularity and its strong-typed syntax for JavaScript. Learn about creating data objects, functions, and data structures through interactive quizzes and exercises.

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

# Composite Data Structures
In the previous sections, we were introduced to the basic structures, types and conditional statements available to us in Reason. What if we could use them to create a more complex data type? 

Well, that is exactly what this section is about. 

# Variants and Lists


The **variant** type is the most powerful and unique tool in Reason. It allows us to group different types together to create a new data type.

The **list** is a structure whose functionality is based on the principles of the variant. It will be the last data structure in this course.

So, without further ado, let's get started with variants.


This section will explore the more advanced data structures in ReasonML.
