Best brainfuck interpreter I could do i… by BuRRak

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

} // 122/140

    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.

Best brainfuck interpreter I could do in 140 characters, super bad code. You need to change the Q variable to your code for it to run. There are no loops or an input, but the output works just fine.

u/BuRRak

The Q variable declaration is there just so you know what to edit, it could be left out as it is not used anywhere in the code again
u/BuRRak

The output also throws a 0 before every other output
