So in this video, I'm going to talk to you about code comments

Modal verbs - A2

and how you can write comments in your code

for just you or your friend and the human beings who

are looking at your code to read, or actually, to like

quickly disable and re-enable certain lines of code,

all sorts of exciting things you could do with code comments.

I'm going to show you how to do that in the p5 web editor,

a feature of a way of writing stuff in your code

executing the instructions and is just there for you

Take a break for a year and you come back

So anything that I write into the p5 web editor with a slash

OK, so this is the green rectangle in the center.

So the idea of a code comment-- and you can see that it is

highlighted, it is gray, it does not have the syntax

but it's important-- line by line, one after another,

That is just there for me the human being to read.

you might say, like, this is where I'm worked on my nose.

And this is where-- this is the code for drawing my chin.

And this is the code for drawing my ears.

And you don't even have to do it as a sentence.

So I could just say, like, you know, red, red circle.

You might also write a note to yourself like later,

And actually, a convention inserting this to write TODO,

But so, there's all sorts of things you could

So I encourage you, easier said than done,

and I don't necessarily follow my own advice,

but I encourage you to get in the habit of writing

It's certainly something that as a teacher

I try to do as much as possible, because I want

to explain the code in line so people can-- looking at it,

can follow what certain pieces are doing.

to code comments that I'm not mentioning.

if I wanted to use noStroke instead of stroke?

What I actually did was I deleted stroke,

And I was able to sort of like undo my way back.

But often, what I want to do-- and I'm going to do that right

So here I'm kind of saving what I had before,

And then now, if I want to put the stroke back,

I can delete that and I can delete the slash slash,

and I can say command slash and the whole thing

I could say command slash again, and the whole thing comes back.

So this is a really just useful technique

while you're working to kind of speed up your workflow.

You can kind of leave some stuff in your code

that you don't want to see, but you might want

And you'll sort of figure out how to manage this best.

is to add things in your code about what you're doing.

might want to consider doing is, you know, code, example,

The Coding Train, maybe you put like a URL in here.

Like this is the kind of thing maybe you have some information

like, and it's what your license is, like please share and use.

You know, there's-- technically, you can add a software license
