heheh: I was playing with the Array Ini… by danny@hille.dk

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.

heheh: I was playing with the Array Initialization Array(10).fill().map((o,i)=>i) shaved off 2 bytes... but then (after mentally padding my own shoulders) [0,1,2,3,4,5,6,7,8,9] 🤦‍♂️

u/danny@hille.dk

c.width=99,x.fillText(a=t%4<2?Array(10).fill().map($=>Math.random()*9|0).join(''):a,22,35)
u/danny@hille.dk

81 bytes but with commas: c.width=99,x.fillText(a=t%4<2?Array(10).fill().map($=>Math.random()*9|0):a,10,35)

77: x.fillText(a=t%4<2?Array(c.width=99).fill().map($=>Math.random()*9|0):a,9,35)

wow u/Xen nice work it also have a nice "burn-in" effect
