A class was written to represent items for purchase in an online store, and a secondclass
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) {

}
}

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());
