“True” and “False” are the two values in a Boolean object. Let us now see how to create a Boolean object:

var val = NEW Boolean(false);

Let us now see an example wherein we will create a Boolean object and return the value. We are using Boolean VALUEOF() method:

<!DOCTYPE html&GT; <html> <body> <SCRIPT> var val = new Boolean(true); document.write( "Value = " + val.valueOf() ); </script> </body> </html>

The output:

Value = true

Here is another example wherein we are returning the string representation of a Boolean value:

<!DOCTYPE html> <html> <body> <script> var val = new Boolean(false); document.write( "String = " + val.toString() ); </script> </body> </html>

The output:

String = false
