JavaScript(12)---Introduction to Classes

Introduction to Classes

JavaScript is an object-oriented programming (OOP) language we can use to model real-world items.

The difference between classes and object syntax is the constructor methods. 
EX:

JavaScript calls the constructor() method every time it creates a new instance of a class.
EX: 

Note: Class method and getter syntax is the same as it is for objects except you can not include commas between methods.
EX:

More examples:

Adding onto getters:

create a static method :

Overview

• Classes are templates for objects.
• Javascript calls a constructor method when we create a new instance of a class.
• Inheritance is when we create a parent class with properties and methods that we can extend to child classes.
• We use the extends keyword to create a subclass.
• The super keyword calls the constructor() of a parent class.
• Static methods are called on the class, but not on instances of the class.

What did I learned today?

In this lesson, I learned more about using JavaScript to code and the method of using classes. I also made some changes to my way of posting. I did lots of screenshots instead of words, because I added comments onto the terminal while I learn, so that I can include all the notes I need in the same screenshots. And I am more confident about using this language now.
