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

# Introduction

The `if` expression is a conditional statement. It allows you to incorporate conditions in your code which need to be *fulfilled* before the code can execute. 

Conditional statements are incredibly powerful as they take the state of the program into consideration and act accordingly. This results in smarter compilation as the compiler is now provided with a decision-making capability.

# Control Flow

Let's look at the control flow of `if`. 

The above flow is showing that if the condition has been fulfilled, the compiler will execute the conditional code and if the condition has not been fulfilled, the compiler will exit that block of code without executing the conditional code.

# Syntax

Before we see the `if` expression in action, let's go over the syntax and see how to write a block of code with `if` using Scala. 

In this lesson, we will go over how to use the `if` expression.
