The strconv.AppendBool() function in Golang is “used to append the boolean values (true or false), based on the value of num2 to num1, and returns the extended buffer”.
Syntax
func AppendBool(dst []byte, b bool) []byte
Parameters
- dst: It is a byte array to which the boolean value (true or false) is to be appended.
- b: It is a boolean value (true or false) to be appended.
Return value
The AppendBool() function returns the extended buffer after appending the given boolean value.
Example 1: How to Use strconv.AppendBool() Function
package main
import (
"fmt"
"strconv"
)
func main() {
var b []byte
// Append a boolean value to the byte slice
b = strconv.AppendBool(b, true)
fmt.Printf("%q\n", b)
}
Output
"true"
Example 2: Passing the second argument to true
If the boolean value is true, it will append the string “true“. If it is false, it will append the string “false”.
package main
import (
"fmt"
"strconv"
)
func main() {
dst := []byte("The answer is: ")
dst = strconv.AppendBool(dst, true)
fmt.Println(string(dst))
}
Output
The answer is: true
That’s it.
