Booleans

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


              1
            
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:

Operator	Logic
`<`	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


              123456789
            
package main
import "fmt"

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