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.

Haha, regex cannot parse an AST... also: }{a = 1
u/tomxor

I take that back, not sure what's going on, can't see much happening in between textarea and eval in iframe.
u/tomxor

Ahh, i get it: function u(t) {} {a=1} the end part is valid if it's an object literal or ES6 destructuring.
u/tomxor

You could actually use this for intialisation variables instead of checking !t... might be smaller
u/tomxor

i.e }{a=1 rather than !t||(a=1) (saves 4 chars)
