JavaScript automatically creates Boolean objects for us as and when our JavaScript programs need, saving us from the worries of creating them. Whenever we assign a vulue of true or false to a variable, JavaScript creates, automatically, a Boolean object for us.

1. true
2. false

A Boolean object has two important methods;

1. toString() and
2. valueOf()

The toString() method of the Boolean object, as its name implies, returns the Boolean object's value as string.
