Exercises

The Matrix

Let's have some fun practicing what we learned about arrays methods.

• Make an array of strings that contains whether or not a person can go to The Matrix movie based on the age (> 18 years).
• File: matrix.js

The Voters

Let's have some fun practicing what we learned about arrays methods.

• Given a serie of potential electors, return an object that represents the election results with the total number of potential voters and actual total number of votes according to three age ranges: from 18 to 25 years old, from 26 to 35 years old, and from 36 to 55 years old.
• File: voters.js

The Calculator Module

A calculator module!

• Create a calculator module that has four functions: "enter", "equals", "list", and "reset". The function named "enter" has to register the input number and/or operator. The function named "equals" has to return the operation's result. The function called "list" shows a history of all operations and its results. Finally, the function called "reset" has to clear operation's and its results history.
• File: calculator.js

Classes (and Polymorphism)

• Create three classes named "Person", "Teacher", and "Student". Each class should have properties and methods as shown at the image below.

• File: classes-polymorphism.js

The Reading List

Exercise obtained from: https://github.com/gSchool/JS-Intro-OOP-Exercises.

• File: reading-list.js

"An object-oriented book-list!

• Create a class BookList

• Create another class called Book

• BookLists should have the following properties:

  • Number of books marked as read
  • Number of books marked not read yet
  • A reference to the next book to read (book object)
  • A reference to the current book being read (book object)
  • A reference to the last book read (book object)
  • An array of all the Books

• Each Book should have several properties:

  • Title
  • Genre
  • Author
  • Read (true or false)
  • Read date, can be blank, otherwise needs to be a JS Date() object

• Every Booklist should have a few methods:

  • .add(book)
    • should add a book to the books list.
  • .finishCurrentBook()
    • should mark the book that is currently being read as "read"
    • Give it a read date of new Date(Date.now())
    • Change the last book read to be the book that just got finished
    • Change the current book to be the next book to be read
    • Change the next book to be read property to be the first unread book you find in the list of books

• Booklists and Books might need more methods than that. Try to think of more that might be useful."
