How Do I Convert a Boolean to a String in Go?

Converting Boolean to String in Go

In Go, attempting to convert a boolean value to a string using string(isExist) leads to an error. To correctly perform this conversion, the idiomatic approach is to leverage the strconv package.

The strconv package provides the FormatBool function, which formats a boolean value into a string representing "true" or "false." The syntax for FormatBool is:

func FormatBool(b bool) string

Where b is the boolean value to be converted to a string.

To use FormatBool, simply call the function with the boolean value as an argument and assign the returned string to a variable:

myBool := true
myBoolString := strconv.FormatBool(myBool)
fmt.Println(myBoolString) // Output: true

Alternatively, you can use a type assertion to convert the bool directly to a string:

myBool := true
myBoolString := fmt.Sprintf("%t", myBool)
fmt.Println(myBoolString) // Output: true

In either case, the result will be a string representation of the boolean value.
