    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.

The Patient Square

u/danny@hille.dk

Arrow functions can be simplified, if you only have one argument you don't need parentheses, and if your result can be expressed as a a single line you don't need curly brackets and return
u/danny@hille.dk

so r can be simplified to: r=_=>Math.random()*400
u/danny@hille.dk

Since you are using the custom random function more than four times, you can go even further with the golf. You can use a trick where you override the valueOf on an object; normally, you need to create an object, but since you don't use the trigonometric function T, you can use it like this: T.valueOf=_=>400*Math.random() x.fillStyle=R(T,T,T) x.fillRect(960+S(T)*400,500+C(t*3)*T,1,5)

u/magna used this trick in d/22152
