Boolean.prototype.toString()

Summary

The toString() method returns a string representing the specified Boolean object.

Syntax

bool.toString()

Parameters

None.

Description

The Boolean object overrides the toString method of the Object object; it does not inherit Object.prototype.toString(). For Boolean objects, the toString method returns a string representation of the object.

JavaScript calls the toString method automatically when a Boolean is to be represented as a text value or when a Boolean is referred to in a string concatenation.

For Boolean objects and values, the built-in toString method returns the string "true" or "false" depending on the value of the boolean object.

Examples

Example: Using toString

In the following code, flag.toString returns "true":

var flag = new Boolean(true)
var myVar = flag.toString()
