HOW?
This is how the dictionnary has been created:
First of all the basics:
![] false
!+[] true
!![] true
+[] 0
+!+[] 1
+!+{} 1
!+[]+!+[] 2
!+[]+!+[]+!+[] 3
Just add '+!+[]' to increment the number => 4 = !+[]+!+[]+!+[]+!+[]
Let's add some more:
[][[]] undefined
{} object
+{} NaN
Embracing arrays:
console.log( [].toString() ) // ""
console.log( (![]+[].toString()) ) // false + ""
And then we've got strings:
![]+[] "false"
!![]+[] "true"
[]+[]+[][[]] "undefined"
[]+[] ""
Basically we'd like to get individual chars.
With the use of brackets, it is possible to treat a string as a simulated array.
"Hello World"[6] => W
![]+[] => "false"
![]+[][1] => NaN ; does not work, we have to surround with parentheses
(![]+[])[1] => "a"
And that's just how it works for every char in the dictionnary!
Of course multiple combinaisons are often possible to access a specific char, but I tried to keep the smallest ones in the dictionnary.
More strings:
[![]]+[][[]] [false]+undefined = "falseundefined"
[]+[]+{} ""+object = "[object Object]"
[![]]+{} [false]+object = "false[object Object]"
10th shortcut:
+!+[]+[+[]] 1+[0] = "10"
We can use the string '10', faster than the number 10:
"falseundefined"[ 10 ] => "i"
"falseundefined"[ "10" ] => "i"
"falseundefined"[ !+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[] ] => "i"
"falseundefined"[ +!+[]+[+[]] ] => "i"
This allows us to access the following chars:
"falseundefined" => i
"[object Object]" => j
"false[object Object]" => c
"NaN[object Object]" => " "
:)
----------------------------
Wrapping this:
http://wtfjs.com/2010/06/09/function-in-ur-string
var _ = "constructor";
_[_][_]("alert('test')")(); // alert('test')
_[_][_]( STRING HERE )();
(![]+[])[+!+[]] 'a'
(![]+[])[!+[]+!+[]] 'l'
(!![]+[])[!+[]+!+[]+!+[]] 'e'
(!![]+[])[+!+[]] 'r'
(!![]+[])[+[]] 't'
(![]+[])[+!+[]]+(![]+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]+(!![]+[])[+[]] 'a'+'l'+'e'+'r'+'t' = "alert"
Let's make an alert:
_="constructor"; // First define the var "_", then use it:
_[_][_]((![]+[])[+!+[]]+(![]+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]+(!![]+[])[+[]]+"()")(); // alerts undefined \o/
([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]] c
([]+[]+{})[+!+[]] o
(+{}+[]+[])[+[]] N
([]+[]+[][[]])[+!+[]] n
(![]+[])[!+[]+!+[]+!+[]] s
(!![]+[])[+[]] t
(!![]+[])[+!+[]] r
(!![]+[])[!+[]+!+[]] u
([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]] c
(!![]+[])[+[]] t
([]+[]+{})[+!+[]] o
(!![]+[])[+!+[]] r
([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]]+([]+[]+{})[+!+[]]+([]+[]+[][[]])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+(!![]+[])[!+[]+!+[]]+([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]]+(!![]+[])[+[]]+([]+[]+{})[+!+[]]+(!![]+[])[+!+[]] "constructor"
Testing this:
_=([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]]+([]+[]+{})[+!+[]]+([]+[]+[][[]])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+(!![]+[])[!+[]+!+[]]+([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]]+(!![]+[])[+[]]+([]+[]+{})[+!+[]]+(!![]+[])[+!+[]]; // Declare "_" var
_[_][_]((![]+[])[+!+[]]+(![]+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]+(!![]+[])[+[]]+'("'+_+'")')(); alerts constructor
_=([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]]+([]+[]+{})[+!+[]]+([]+[]+[][[]])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+(!![]+[])[!+[]+!+[]]+([]+[]+{})[!+[]+!+[]+!+[]+!+[]+!+[]]+(!![]+[])[+[]]+([]+[]+{})[+!+[]]+(!![]+[])[+!+[]];
_[_][_]((![]+[])[+!+[]]+(![]+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]+(!![]+[])[+[]]+'("'+(![]+[])[+!+[]]+(![]+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]+(!![]+[])[+[]]+'!")')(); alerts alert!
