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.

Learn Scala from Scratch

*Mutable* is defined as something that can be altered, and mutable variables are just that; variables whose values can be altered. 

## Declaring a Mutable Variable

To declare a mutable variable, we use the `var` keyword. Let's take the same example we used in the previous lesson.
We have a variable `message` which is assigned a `String` value.
