Introduction
A Boolean object is a wrapper class and a member of global objects. It is used to convert non-Boolean values into Boolean values. It has two values: true and false. The Boolean object returns false when the object is passed with values, such as, 0, “ ” (empty string), false, null, undefined, and Not a Number (NAN) values. The Boolean object can be created in the following ways:
