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

## Keeping Track of Values
Storing data in an identifier is essential for almost any language. Identifiers facilitate the flow of information throughout a program. If we have a value that is being used in several places, it would be impractical to hardcode it again and again.

Attaching an identifier to the value would make the code more concise, more readable, and more reusable.

## The `let` Identifier

The `let` keyword is used to assign, or *bind*, a name to a value. This value can now be accessed and modified through the corresponding name.

Apart from simple data types, `let` bindings can also be assigned to the results of expressions. The basic syntax for a `let` binding can be seen below:
