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

*Immutable* is defined as *unchangeable* and is precisely what an immutable variable is; unchangeable. 

Immutable variables are basically like constants; once they are assigned a value, that value can never change.

## Declaring an Immutable Variable

To declare an immutable variable, we use the `val` keyword. Let's create a variable named `message` that is assigned a `String` value.
