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());
