u(t) is called 60 times per second. t: Elapsed time in seconds. S: Shorthand for Math.sin. C: Shorthand for Math.cos. T: Shorthand for Math.tan. R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5) c: A 1920x1080 canvas. x: A 2D context for that canvas.

    Very useful shortcuts, I'll have to use them in future. ...I'm thinking like a C programmer - in the C standard the order in which arguments are evaluated is unspecified; apparently the ES standard strictly defines order-of eval to be the intuitive left-to-right order. Good to know!

    Ha, it feels "wrong" to set fillStyle 9 times in a row. But a great way to eliminate that last little character!

    #default

    When you're out of characters you can shave "legally", you have to start compromising and enter the "wrong" and/or "meh, it's just a good approximation" territory :)

    Like Math.PI * 2 === 7

    Heh, totally. :D

    hack to save 2 chars: x.fillStyle=R(-D*9e7)
  • u/pythech
    I guess that's "meh" territory

    @pythech nice!
