The toString() method returns a string representing the specified Boolean object.
Boolean.prototype.toString()
Try it
Syntax
toString()
Return value
A string representing the specified Boolean object.
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
Using toString()
In the following code, flag.toString() returns "true":
var flag = new Boolean(true); var myVar = flag.toString();
