    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.

Can you explain how you are declaring your variables? specifically in "8+i%2*4+2*o+C" you reference 'o' and 'C' before they have even been declared -- I think.
u/pavel

for(i=9;i--;/*code here*/)/*runs after code here*/
u/ivylab

Exactly the other way around, isn't it? First the code after the bracket runs and then the code in the brackets. Your declaration is behind them. c.width=1e3;for(i=9;i--;x.fillStyle='red')x.fillRect(112*i,0,100,1000) shows that too.
u/sigveseb

Or in other words, a for loop for(A; B; C) D; will run the different parts in this order: A B D C B D C B D C .. B
u/ivylab

Exactly what I think and meant. Well written @sigveseb

u/New_Core

u/katkip

instead of that let you can use i=4e3,j=s=0
u/pavel

The let is only there for performance to use up free chars. j and s don't need initializing. But i at 4e3 cant do 60fps without let on my machine.
u/pavel

Can just do i=2e3 if you are remixing and need chars
u/katkip

oh, i understand

u/sigveseb

very nice
u/gambit

hi im new! can you explain me "c.width|=0" what does it do? thanks
u/DataMeta

Welcome! It's a shorter way of clearing canvas pixels/state. Can be chained like so: for(c.width|=n=i=256;i--;). It can't be done here because we must clear the canvas before scaling it
u/includeRubiks

so cool
