Don't we have to import Token.js before using "new Token()"?

Or did Ashley just skip it for now?

Thanks!

This is confusing, I agree.

The HTML file "imports" both of the files, so therefore they are able to access each others' variables/classes.

This is my interpretation of how it works, if I'm wrong, please tell me (to fellow students)

Think of it like this: here's my HTML:

<!DOCTYPE html>
<html>
    <head>
        ...
    </head>
    <body>
        ...
        <script src="file1.js"></script>
        <script src="file2.js"></script>
    </body>
</html>

Here's my JS:

file1.js 
const myNumber = 12;
file2.js 
console.log(myNumber);

Behind the scenes, the HTML reads the file and merges the JS code into the HTML:

<!DOCTYPE html>
<html>
    <head>
        ...
    </head>
    <body>
        ...
        <!-- file1.js -->
        <script>
            const myNumber = 12;
        </script>

        <!-- file2.js -->
        <script>
            console.log(myNumber);
        </script>
    </body>
</html>

Now you can see how they are able to access each others' variables. Sure, they are in different <script> tags, but HTML considers them to be in the same "scope"

I hope this helps. ;)

You're right, Alexander! The classes files are indeed imported in the HTML

<script src = "js/Game.js"></script>
<script src = "js/Board.js"></script>
<script src = "js/Space.js"></script>
<script src = "js/Player.js"></script>
<script src = "js/Token.js"></script>
<script src = "js/app.js"></script>

I didn't check there before I ask, my bad.

Thank you!
