Title Body

this question is difficult to summarize in a question title UPDATE I created a JSFiddle that builds an obfuscated string out of your input based on the letters extracted from this question: You can access it here , or would a gist be easier? I recently came across a fun bit of obfuscated JavaScript in this profile that looks like this: javascript:[[]+1/!1][1^1][1>>1]+({}+[])[1<<1^11>>1]+([]+!!- [])[1<<1]+[/~/+{}][+!1][-~1<<1]+([]+/-/[(!!1+[])[1>>1]+(!!1 +[])[1<<1^1]+(!1+[])[1|1<<1]+(!!1+[])[1^1]])[1^11<<1]+([,][ ~1]+[])[1-~1]+[[]+{}][!1.1%1][11111.1%11.1*111e11|!1]+(/1/+ 1/[1<1][1%1])[1^11]+[[],[]+{}][1][+1]+(/<</[1]+[])[1/1.1&1] Sorry to ruin the surprise but when this is evaluated it returns this: "I love you" in Chrome "I lone you" In Firefox "I lo[e you" in IE10 The way this works when broken out, is to generate a series of messages and to pull letters out of them like so (using the "I" as an example): []+1/!1 returns "Infinity" then [[]+1/!1] creates this array: ["Infinity"] then [[]+1/!1][1^1] Takes the first (1^1 == 0) element of that array "Infinity" finally [[]+1/!1][1^1][1>>1] Takes the first (1>>1 == 0) char of that string "I" Other strings that are generated include: ({}+[]) -> "[object Object]" (where the space comes from) ([]+!!-[]) -> "false" (used for it's "l") [/~/+{}][+!1] -> "/~/[object Object]" (this is used for an "o") (/<</[1]+[]) -> "undefined" I was interested in finding a replacement for the "n" and "[" and came up with this: String.fromCharCode(('1'.char
