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.

# Types of Logical Operators

Logical operators are operators that perform logic operations such as the Logical *AND* and Logical *OR*. They take `Boolean` type operands and yield `Boolean` type results. Below is a list of the logical operators supported by Scala.

| **Operator** |**Name**| **Use**     |
|------ |---|------|
|`&&`|Logical AND| If both the operands are not false then the result is `true`|
|`||`|Logical OR| If any of the two operands is not false then the result is `true`|
|`!`|Logical NOT| Reverses the logical state of its operand. If a condition is `true` then the Logical *NOT* operator will make it `false`|

>`!` is a unary operator, i.e. it takes one operand.

# Follow the Rules

Below, you'll find a list of the reduction rules for logical operators. The list is handy as it will summarize how each operator reduces expressions into their final form.

*exp* is an arbitrary expression that can be replaced with an operand of type `Boolean`. The operand can be `true` or `false` itself or can be an expression that reduces to `true` or `false.`

In the following lesson, you will be introduced to logical operators.
