#confetti remix! Had to go to squares t… by lionleaf

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.

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

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.

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