new operator

new constructor()

Creates a new, initially anonymous, object and calls the function identified by the

constructor parameter. The new operator passes to the function any optional parameters in

parentheses, as well as the newly created object, which is referenced using the keyword

this.

The

constructor function can then use this to set the variables of the object.
