Consider following code snippet:

var bool = new Boolean(false);
if (bool) {
   console.log('Hello');
} else {
   console.log('Error');
}

What will be printed to the console?

new Boolean(false) returns an object which is not null. Non-null objects are always truthy. Example:


var bool = new Boolean(false);
typeof(bool); // object
