// You can find the Turtle API reference here: https://turtletoy.net/syntax
Canvas.setpenopacity(1);

// Global code will be evaluated once.
const turtle = new Turtle();
turtle.penup();
turtle.goto(-50,-50);  // this is the starting point
turtle.pendown();


// start simple don't worry about a loop

turtle.forward(100);
turtle.right(90);

turtle.forward(100);
turtle.right(90);

turtle.forward(100);
turtle.right(90);

turtle.forward(100);
turtle.right(90);
