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

# The Definition
**Currying** is the process of dividing a function with multiple parameters into separate functions for each parameter.

A function can be curried when we provide it with fewer arguments than it originally needs and assign this incomplete call to a new `let` binding. 

Now, we only need to pass the remaining arguments to the new function.

>**Note**: Passing more arguments than the function actually has, will produce a compile-time error. Currying only works when we provide an incomplete number of arguments.


# Example
Let's make things clearer with the help of an example.

In this lesson, we'll learn what currying is.
