    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.

#confetti remix! Had to go to squares to squeeze color in, but should be possible to golf back to circles

u/BalintCsala

You don't have to close the hsl function
u/redactedhoptional

You can use a template string in the color string, so hsl(${9*i},99%,50%, it saves 1 character. You could also make it translate(960,540) so it is correctly centered.
u/redactedhoptional

Also also, you can remove fill(), and round the -3.88 to -3.9 to save a character.

.618 is an approximation to the golden ratio. Putting .5 == 1/2 will create 2 spokes. Similarly .6 == 3/5 will create 5 spokes.

That one works if you remove the fillStyle ¯\_(ツ)_/¯.

Proof-of-concept of using valueOf to prevent function call parenthesis (()) to save space when a function is used at least 5 times.
