    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.

Bubble Sort Caffeinated

u/cantelope

neat! i like your code where map returns Math.random. this works fine albeit the syntax is unconventional. i've often used the same abbreviated syntax in event listeners, to the horror of classically educated devs :D e.g. window.addEventListener('load', myLoadfunc), vs window.addEventListener('load', () => {...}). it's all the same to me, but not some people apparently heh
u/magna

Fun ensues when a binary function uses the index arg: Array(5).fill(2).map(Math.pow)

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)
