Learn the syntax, data types, and operations essential for programming in Scala

Become a Scala Developer

In this module, we will learn Scala from the ground up. This module aims to teach us how to write basic programs, assuming we have no prior knowledge of the language. We will start with a brief introduction to Scala to understand its functionality and applications. We will then move discuss the key features and functions of the language (data types, functions, classes, etc.) in detail. In the end, we will have all the basic knowledge of how to program in Scala.

## Task

In this challenge, you were provided a primary color and you had to match it to its complementary secondary color.


## Solution

Let's go over the solution step-by-step.

* The first thing you had to figure out is that this problem requires a `match` expression.

* Next, you had to figure out the number of cases the `match` expression would require to cover all the possible scenarios. We had one case for each primary color along with a default case if the input was anything but a primary color.
```
case "blue" => print("orange")
case "yellow" => print("purple")
case "red" => print("green")
case _ => print("not a primary color")
```



You can find the complete solution below:

>You were required to write the code from **line 3** to **line 8**.
