(1 - 6 are the same as on the previous lab, but creating classes using ES6 syntax instead of constructor functions)
a. Write a class called Person that has 3 properties: a first name, a last name and a middle name. Create 2 instances of a Person. Print one of their first names.
b. Write a method in Person called fullName that will return a formatted string of an instance's full name. Call this method on both the instances you created in part a.
a. Create a class called Book that has properties title, author and rating. Create some instances of Book.
b. Add a method to Book called isGood that returns true if its rating is greater than or equal to 7
a. Create a Dog class with four properties: name (string), breed (string), mood (string), and hungry (boolean).
b. Add a method called playFetch. It should set the dog's hungry property to true, set its mood property to playful, and log "Ruff!"
c. Add a method called feed. If the dog is hungry, it should set hungry to false and print "Woof!" If the dog is not hungry, it should log "The dog doesn't look hungry"
d. Add a method called toString that returns a description of the dog:
There are three common scales that are used to measure temperature: Celsius, Fahrenheit, and Kelvin:
C = (F - 32) / 1.8 F = 1.8 * C + 32 K = C + 273
a. Make an object called freezingPoint that has three properties: celsius, fahrenheit, and kelvin. Give them all values equal to the freezing point of water.
b. Make a class called Celsius that has one property: celsius, and two methods getFahrenheitTemp, and getKelvinTemp.
let outsideTempt = new Celsius(10.0)
outsideTempt.celsius //returns 10.0
outsideTempt.getKelvinTemp() //returns 283.0
outsideTempt.getFahrenheitTemp() //returns 50.0c. Give Celsius a method called isBelowFreezing that returns a Bool (true if the temperature is below freezing).
a. Create a class called Movie that has properties for name, year, genre, cast, and description. Create an instance of your Movie
b. Create an method inside Movie called blurb that returns a formatted string describing the movie.
Ex: "Borat came out in 2006. It was an odd film starring Sacha Baron Cohen as a man named Borat who was visiting America from Kazakhstan."
Write a constructor Vector that represents a vector in two-dimensional space.
It takes two number arguments: x and y parameters, which it should be saved to properties of the same name.
Give the Vector prototype two methods, plus and minus, that take another vector as an argument and
returns a new vector that has the sum or difference of the two vectors’ (the one in this and the parameter) x and y values.
Add a method getLength to the prototype that computes the length of the vector ;
that is, the distance of the point (x, y) from the origin (0, 0).(a^2 + b^2 = c^2)
var v1 = new Vector(1, 2)
var v2 = new Vector(2, 3)
console.log(v1.plus(v2));
// => Vector {x: 3, y: 5}
console.log(v1.minus(v2));
// => Vector {x: -1, y: -1}
var v3 = new Vector(3, 4)
console.log(v3.getLength());
// => 5a. Make a class called Car with properties make and model. Create an instance of a Car
b. Make a class called Bike with properties gears and hasBell. Create an instance of Bike
c. Give each class a static method called numberOfWheels that returns the number of wheels (2 for bikes, 4 for cars). Why does it make sense for this to be a static method instead of an instance method?
a. Make a class called Vehicle with properties color and name. Give it a method called makeSound which logs "WHHOOSSSH" to the console
b. Modify your Car and Bike classes from Question 7 to extend the Vehicle class.
c. Create a new Bike instance that has a color of "green" and name "Bikey McBikeface"
d. Create a new Car instance that has a color of "red" and name "Carry McCarface"
