to talk to you about something called inheritance.

Inheritance in the context of object oriented programming

there are three core foundational principles

that is the topic of this particular video,

and there is also the concept of polymorphism

And I have made videos on all of these topics before.

were all made in the processing programming environment

Now I am talking about exactly the same thing

And I have already made a whole set of videos about

encapsulation and object orineted programming in JavaScript

making use of something called ES6 classes.

So one of the things you have to get used to

if you choose to spend you life programming in JavaScript

and there's 500 different ways to do the same thing

and everybody's got their opinion on which way is best.

And a lot of my older videos used a prototype

and you'll find those in older coding challenges

and you'll even find a set of videos about

how to do object oriented programming that way

and even one about how to do inheritance that way.

And if you watch that you're a true champion

and I have no idea if I explain that well.

Oh, sorry, ES6 being the version of JavaScript

It is currently 2019 while I'm recording this.

But it is now pretty widely supported across all browsers.

because I am demonstrating this in the context

then I can have a variable somewhere else,

the distinction between the class and the object

So the cookie cutter isn't actually a cookie.

It's a thing that you can make cookies with.

So this is a template, there's no particle object here.

This is just a template to make actual particle objects.

saying new particle means execute something inside the class

So I'm kind of I guess by accident reviewing

to get myself into the inheritance topic.

details and examples about this in the other videos.

So let's go over to the code for a second.

And this dot is an example of a particle object.

and the update function changes the x and y randomly

and the show function draws it as a boint.

It would be great if there was a function called boint,
