Right now it's very simple playground created for teaching programming. As first intro to programming use plotting functions.

You can introduce mathematical functions:

$$f(x) = 2x + 1$$

and show how it's created in JavaScript by using this URL that will create new Sketch:

https://p5.javascript.org.pl/?include=coord.js&main=plot.js&base=fn.js

it will load this JavaScript code:

function f(x) {
    return 2 * x + 1;
}

And plot.js script that is hidden with help of coord.js will plot that function. After the person get familiar with functions, JavaScript keywords and expression (connected to her/his knowledge about functions in math) he can learn more about JavaScript and P5.js.
