    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.

#circlechallenge No trig, no direct square root: Just using the Pythagorean theorem + the fact that sums of odd numbers give perfect squares

How is }{ valid code? What is it doing? It seems to make X=Y=500 work.
u/KilledByAPixel

that basically ends the function and sets X and Y before it even runs the loop, kind of a cheap trick i don't often use but can save a byte or two

#circlechallenge Monte Carlo Method

u/DaSpider

Using only good old Pythagoras. This method can be used to estimate π ≈ 4*(number of points in the circle / total number of points) // t?1:d=g=0;A=Array(s=6e3).fill().map(Math.random);for(i=s;i--;(a**2+b**2)**.5<=1?d++:1)a=A[i],b=A[s-i];g+=s;throw(4*d/g)
