    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)

59B checkered pattern ! new ultra-golf challenge ! rules proposed on discord

u/New_Core

I didnt read the rules but here is a 48B for(i=166;i--;)x.fillRect(i%24*90,i%14*90,90,90)
u/pavel

Would be good to put the rules here... Can the scale be not 90? Seems like a bad number. 120 fits nicely horizontally and vertically, I'd choose that. Or a power of two for possible bit twiddling.
u/metamero

rules of this one: - full render on first/each frame - full resolution - exact 12 squares on vertical

11B variable reuse init demo

Show more comments…
u/tomxor

Good for integer init, this is because bitwise operators in JS coerce all non-number types to 0 (but also temporarily cast to int32 destroying floats)
u/tomxor

this includes trully undefined (not undefined _type_), so you can use it to init non existant properties on an object/function e.g u.foo=-~u.foo
