Booleans are an essential data type used to represent truth values (true or false) in logical expressions.

A boolean is denoted by the keyword bool and can have either the value true or false.

index.go

index.go

copy

var myBool bool = true

The default value of a boolean is false.

Booleans become especially useful when we need to store the results of logical expressions. Logical expressions are constructed using logical and/or comparison operators.

While logical operators and expressions will be explored in detail in the next section, here's a brief introduction to the three comparison operators in Go:

OperatorLogic
<Less Than
>Greater Than
==Equals To

Here's a simple example of how the result of a logical expression is stored in a boolean:

index.go

index.go

copy
123456789
package main import "fmt" func main() { var value int = 7 var myBool bool = value > 5 fmt.Println(myBool) // Outputs 'true' }
