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

# Problem Statement
In this exercise, you must create the `convertTemp()` function which converts temperature from *Celsius* to *Fahrenheit*.

 Here is the conversion formula:


$$ F = C * 1.8 + 32 $$

The temperature will be of the `float` type.

## Sample Input
```
C = 40.5
```
## Sample Output
```
F = 104.9
```

# Coding Challenge
This problem is all about connecting functions with arithmetic operations. Pay attention to the syntax you write for the conversion formula, as well as the value returned by the function.

If you feel stuck, you can always refer to the solution review in the next lesson.

Good luck!
