  • u/magna

    very nice
  • u/gambit
    hi im new! can you explain me "c.width|=0" what does it do? thanks
  • u/DataMeta
    Welcome! It's a shorter way of clearing canvas pixels/state. Can be chained like so: for(c.width|=n=i=256;i--;). It can't be done here because we must clear the canvas before scaling it
