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