Want to print out all odd numbers from 1 to 100? Easy:

for(_=[];_<+!![]+""+[]*[]+[]*[];_++)(_%+(!![]+!![])?console.log(_):[]);

Actually, I prefer this one: for(_=[];_<+!![]+""+[]*[]+[]*[];_++%+(!![]+!![])?[]:console.log(_));

Or this one without the "undefined" when run in a browser console:

for(_=[];_<+!![]+""+[]*[]+[]*[]-!![]-!![];_++%+(!![]+!![])?[]:console.log(_));_+!![]

Wtf people, can somebody explain?

[–] Naich@lemmings.world 1 points 5 months ago

_ is a variable name, [] becomes 0 when converted to an integer, !![] becomes 1. The + "" + means that the integers 1, 0, 0 get converted to a string - "100", which gets converted back to an integer because it's in the for loop. And there's various other horrible conversions going on to make it all work.
