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

Previously, we learned how to create tuples containing various data objects called components. The components of a tuple, are indeed, immutable; but this does not mean that we cannot use them.

**Pattern matching** is a technique for accessing the contents of a tuple. All we have to do is create a pattern which corresponds to the values in a particular tuple. In this pattern, we will define identifiers for the values in the tuple. 

# Creating a Pattern
Let's create a pattern and map a tuple's components to it:

In this lesson, we will be introduced to the concept of pattern matching and how it relates to data structures in ReasonML.
