    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();
