    Nice ^^ I like how you used fromCodePoint instead of fromCharCode to shave bytes. Btw, you can replace (i?0:27) with !i*27 to make the code even shorter
  • u/sigveseb
    for..of can make this quite a bit shorter! x.fillRect(i=0,87,W=c.width=310,3);x.font='49px A';for(a of'🚂🚃🚃🚃🚃🚃🚃')x.fillText(a,q=W-t%4*W+i++*46,90+S(q/15))

    stiaje tried to create a dweet with unicode characters in the code, and it didn't work.. why does it work now? :D
  • u/iverjo
    Maybe it was a problem with base64 encoding/decoding @ arkt.is/t/

    Nice, is the compression worth the bootstrap overhead?
  • u/iverjo
    Crazy stuff. How does it work?
  • u/3bl3gamer
    No, it does not. Decompressor doubles characters number, but takes 75 characters by itsef. So no profit, just making some unreadable code even more unreadable :-)
  • u/3bl3gamer
    It works by converting N utf-16 characters to N*2 bytes and then converting this N*2 bytes to N*2 utf-8 characters. This N*2 characters is JS code.
  • u/iverjo
    A for effort
