- Define Object .arrow_forwardJavascript Question: Part 1 Design a Pet object. A Pet is created with a language argument string and a stomach represented by an array. The Pet should support functions: eat() and speak(). Use the prototype property to define your object's interface. eat(food) will store the passed argument into its stomach and return what it has eaten thus far. speak(sentence) will simply return the passed in phrase. function Pet(language) {// create stomach// set language}// takes a food_item STRING and returns everything eaten so far ARRAYPet.prototype.eat = function(food_item) {// ... complete }// takes in a sentence STRING and returns the passed in sentence STRING with no changePet.prototype.speak = function(sentence) {// ... complete} You may also use the newer class notation. Part 2 Create an object, Dog, that implements the Pet interface and takes the same argument language. Dogs eat the same way all pets do. Dogs speak differently.
