On: JSFuck – Write any JavaScript with 6 Characters: []()!+

[bargl]

It looks like the generator is suboptimal, but still really cool.

(![]+[])[+!+[]] evaluates to "a" as well. It looks like it turns it into an array twice.

It goes +!+[] === 1 then [+!+[]] === [1] then +[[+!+[]]] === 1 then [+[[+!+[]]]] === [1]

[ygra → bargl]

Maybe one could run the output through Closure Compiler to get a bit better code ;-)

(Ok, tried it, it evaluates plenty of numbers on its own already which increases the character set. Not nice).

Ah! You're right. Confusing.

Also confusing that "false"[[1]] works.
