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 problem, you have to update the value of two mutable integers, `x` and `y`. The value of `x` will be incremented by `5`, whereas the value of `y` will be multiplied by 10. 


## Sample Input
```reason
x = 20, y = 3
```

## Sample Output
```
x = 25, y = 30
```

# Coding Challenge
Try to understand all the steps necessary to reach the final goal. This exercise isn't too difficult, so it shouldn't take long. 

Remember, the `x` and `y` variables have already been defined as `ref` wrappers for the integer type. You will not be able to see them. All you have to do is modify the values wrapped inside them.

If you feel stuck, refer to the solution review for help.

Good luck!



In this exercise, we will mutate the values of two integers.
