What is the output when executing the code above?

A class was written to represent items for purchase in an online store, and a second class. Representing items that are on sale at a discounted price. The constructor sets the name to the first value passed in.

The pseudocode is below:

Class Item {

constructor(name, price) {

… // Constructor Implementation

}

}

Class SaleItem extends Item {constructor (name, price, discount) {

…//Constructor Implementation

}

}

There is a new requirement for a developer to implement a description method that will return a brief description for Item and SaleItem.

Let regItem =new Item(‘Scarf’, 55);

Let saleItem = new SaleItem(‘Shirt’ 80, -1);

Item.prototype.description = function () { return ‘This is a ’ + this.name; console.log(regItem.description()); console.log(saleItem.description()); SaleItem.prototype.description = function () { return ‘This is a discounted ’ +

this.name; }

console.log(regItem.description());

console.log(saleItem.description());

What is the output when executing the code above?
