So I have so far made three videos in this series

about learning to code from the very beginning

you what happens when you make a mistake, which I really

That's the thing I really should be showing you right from

And both of these things are fundamental to how

that you might work on over a period time

So let's first look at the console and errors.

I've been talking about this is where you write your code,

and this is where you see the result of your code.

that are things that are related to what's

happening in your code that might be a mistake

or something that you add that you want to specifically put

I'm going to say Print, and I'm going to say Hello.

And I'm putting this in Setup because I want this just

And this again, I will come back to later.

So this being in the code, suddenly in the console,

The idea of the console is not something.

So if you're making a project that you imagine users

using, like a game, you wouldn't put the score of the game here.

You would want to draw the score somewhere on the canvas,

put the score below the canvas, something for the user

what the score of the game is and kind of like for yourself

is for you, the person who's writing the code,

or your friend who you're sharing the code with,

I mean, it's something that anybody using the p5 web editor

But when you've finished it and you put it

that console wouldn't necessarily appear.

So in addition to be on to put your own messages,

anything that you do wrong is going to be down there.

noStroke also doesn't even have any arguments in here,

like, it's just open and close parentheses,

If I get anything wrong, like if I delete this comma,

Now I'm also getting error messages in here.

if it tells you exactly what's wrong and you can--

Uncaught SyntaxError missing parentheses after your argument

The thing that's generating the error, the web editor,

the JavaScript language, the browser, all of these pieces

So the nice thing is they can see like, oh, I

I'm going to change this from strokeWeight with a capital W

to strokeweight with a lower case W. And this,

I'm not getting such a great error message,
