Class keyword- constructor inheritance
// Part 1
// Create a class called User using the ES6 class keyword.
// The constructor of the class should have a parameter called `options`.
// `options` will be an object that will have the properties `email` and `password`.
// Set the `email` and `password` properties on the class.
// Add a method called `comparePasswords`. `comparePasswords` should have a parameter
// for a potential password that will be compared to the `password` property.
// Return true if the potential password matches the `password` property. Otherwise return false.
class User {
constructor(options) {
this.email = options.email;
this.password = options.password;
}
comparePasswords(password) {
return (this.password === password);
}
}
// Part 2
// Create a class called `Animal` and a class called `Cat` using ES6 classes.
// `Cat` should extend the `Animal` class.
// Animal and Cat should both have a parameter called `options` in their constructors.
// Animal should have the property `age` that's set in the constructor and the method
// `growOlder` that returns the age after incrementing it.
// Cat should have the property `name` that is set in the constructor and the method
// `meow` that should return the string `<name> meowed!` where `<name>` is the `name`
// property set on the Cat instance.
class Animal {
constructor(options) {
this.age = options.age;
}
growOlder() {
return ++this.age;
}
}
class Cat extends Animal {
constructor(options) {
super(options);
this.name = options.name;
}
meow() {
return `${this.name} meowed! where ${this.name} is the name`;
}
}
