    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.

quest for the most lines in a 6 byte dweet? anyone want to try further

Show more comments…
u/erin

ok, i have a scoring system
u/erin

divide the amount of bytes by the lines
u/erin

so my score is 1.5 (smaller = better)
u/DaSpider

throw loop
u/erin

ohh sick, nice one
u/Xen

throw u+=u
u/DaSpider

We have a winner
u/erin

u/xen, technically breaks the "rules" i set, it has to throw everything at once
u/Xen

oh :-( ok...
u/Xen

throw [...Array(5e3).join(loop)]
