First I could not find any documentation on the set method. but then later i was reading something about Uint8Array, and low and behold: set is a part of the javascript typedArray https://developer.mozilla.org/en-US/docs/Web…

skoehler stole your dweet
u/warbino

ummmm someone stole your code............... his name is skoehler .
u/cantelope

@warbino, @thenize. this may be the last time you are reminded about the spirit of this platform. we do not dwell on "stealing" of code, as remixes are a provided function of the site. Your pattern of edge comments itself, since it continues, may be considered abuse. Unless you stop, there may be action.
