    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.

nice!
u/DirtyDan

Don't know what I was thinking having "+960+C(t)*i" in the first arc parameter -_- ... 11 extra characters!
u/DirtyDan

nvm, the +960 was necessary, not the "+C(t)*i"... 7 extra characters.
u/Purpzie

This is so beautiful.

u/cantelope

neat! i like your code where map returns Math.random. this works fine albeit the syntax is unconventional. i've often used the same abbreviated syntax in event listeners, to the horror of classically educated devs :D e.g. window.addEventListener('load', myLoadfunc), vs window.addEventListener('load', () => {...}). it's all the same to me, but not some people apparently heh
u/magna

Fun ensues when a binary function uses the index arg: Array(5).fill(2).map(Math.pow)
