Objects in many
Step by step
Solved in 2 steps
- A. Which statement about object-oriented programming in JavaScript is correct? a. JavaScript programs may contain just two kinds of objects: native and host. b. Object-oriented programming refers to the creation of reusable, anonymous functions. c. The code and data within an object cannot be read or modified directly by other programs. d. The encapsulation provided by objects increases complexity but also increases speed. B. Suppose you have written JavaScript constructors for two object classes calledClassAandClassBand then the statementClassA.prototype = new ClassB();.ClassBcan use the value returned by one ofClassA’s methods in one of its own methods becauseClassBinherits all the properties and methods ofClassAin this situation.

You must define classes that support the functionality specified by the interface:. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or any private methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received (rented) by the customer. There are twoplans a customer can have: UNLIMITED and LIMITED. UNLIMITED allows a customer to receive as many mediaas they want; LIMITED restricts the media to a default value of 2 (this value can be change via a media rentalclass method).A movie has…
