    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.

hmmm

u/tomxor

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)

u/Xor has a very clean 35b circle too: d/22669. There are some shorter circles, but they're blurrier: d/24291, d/24311. If you allow throw, you can get really tiny: d/18442

I'm not seeing it on Windows 10. Must be a font issue. u/KilledByAPixel, thanks for explaining it.
