How to Convert a Boolean Value to a String in Go?

Converting bool to String in Go

When attempting to convert a bool value (e.g., isExist) directly to a string, the string(isExist) approach may fail. To perform this conversion effectively, Go recommends leveraging the strconv package.

The strconv package provides a dedicated function specifically designed for converting bool values to strings: strconv.FormatBool(v).

import "strconv"

func main() {
    isExist := true
    str := strconv.FormatBool(isExist)
    fmt.Println(str) // Output: "true"
}

The strconv.FormatBool(v) function returns a string representing the string form of the boolean value v. The syntax is simple and straightforward, making it easy to incorporate into your Go code.

This idiomatic approach ensures consistency and adheres to Go's best practices for converting boolean values to strings. It eliminates the pitfalls of other methods and provides a clean and reliable way to handle these conversions.
