    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.

u/rep_movsd

OMG I had no idea you could just put a series of co-ordinates for Path2D with just M
u/jylikangas

I've used this Path2D trick a lot in Dweets. Explained here: http://jsriffs.blogspot.com/2019/03/js1k-201…

Nice! and Welcome to Dwitter :-)
u/danny@hille.dk

suggestion: 7 * Math.PI / 180 can be written as an approximation const: .12 without any significant loss
u/danny@hille.dk

also whenever the order of execution isn't important you can shorten for loops like this: for(i=100;i--;); becaus 0 is falsy, so when i reaches 0 the loop exits
u/danny@hille.dk

you an free up space, so you can center the Explotion like this: c.width=640,x.translate(320,180);for(i=99;i--;)for(z=99;z--;x.rotate(.12))x.fillRect(z*t+S(t)*10,i*t+C(t),2*S(i),5*S(z))
u/danny@hille.dk

this example adds some additional golfhing tricks: 99 is almost 100 :-), use the free slot in the for loop to execute code, you would otherwise execute inside the for loop
u/sanco

Thanks a lot danny! I'm new on this so really appreciate the comments.
