    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.

Golf dweet re-imagined with transforms instead of font changes. Turns out this isn't even shorter.

u/f8f82804

I like this! Might not be shorter but the ball is a good touch. #golf

Tiny tweak, using the fact that x.l=translate,l(...),l(...) saves two characters. This is the equivalent of x[l='translate'](...),x[l](...) if you're already using with(x).

Inspired by d/9635, but with a very different approach: no looping or explicit state #functional #golf

u/donbright

how???????
u/f8f82804

Looping is done by recursion and state is managed with the context's transform stack
u/Toby

Hi, could you explain what x[l='translate'] is accessing, please?
