Perlの書き込み専用と JS書き込み専用

長谷川洋介によるこの小さなJavaScriptは、アラート（1）を実行します。

（É= [Å= []、μ=！Å+Å] [μ[È=-〜-〜++Å] +（{} +Å）[Ç= !!Å+μ、ª=Ç[Å ] + [+！Å]、Å] +ª]）（）[μ[Å] +μ[Å+Å] +Ç[È] +ª]（Å）



どのように機能しますか？





簡単にするために、

Å-> Int_1

É-> f_sort

È-> Int_3

µ-> B_false

ª-> Str_rt

Ç-> Str_truefalse



取得するもの：

（f_sort = [Int_1 = []、B_false =！Int_1 + Int_1] [B_false [Int_3 =-〜-〜++ Int_1] +（{} + Int_1）[Str_truefalse = !! Int_1 + B_false、Str_rt = Str_truefalse [Int_1 ] + Str_truefalse [+！Int_1]、Int_1] + Str_rt]）（）[B_false [Int_1] + B_false [Int_1 + Int_1] + Str_truefalse [Int_3] + Str_rt]（Int_1）
