https://turtletoy.net/ Turtletoy is created by Reinder Nijhoff (@ReinderNijhoff).

Turtletoy allows you to create generative art using a minimalistic javascript Turtle graphics API. You can only create black-and-white line drawings on a square canvas. By offering a very restrictive environment we not only hope to stimulate creativity, we also make sure that the turtles can (at least theoretically) be plotted using a simple plotter.

You can read the Turtle API reference first or directly start writing your own turtle here.

 Each turtle can be exported as SVG, suitable for high-res printing or a plotter.

"Did you know you can also write the centeredCircle function like this
```
function centeredCircle(x,y, radius, ext =360) {
  turtle.jump(x,y-radius);
  turtle.circle(radius, ext);
}
```"

console.log("Hello world!");

Given two Cartesian coordinates, here’s how you compute the distance between them:

function pointDistance(x1, y1, x2, y2) {    return Math.hypot(x1 - x2, y1 - y2);  }  

Here’s how you might use this function:

pointDistance(0, 0, 3, 4);  // => 5     pointDistance(100, 7, 200, 7);  // => 100

for (var i = 0; i < 9; i++) {   
  console.log(i);   
  // more statements  }
