Hello there,

I need little help with this cryptic piece of js code:

(function(c){f=0; for (i in c) f = c[i] = (f-c[i]); return String.fromCharCode.apply(null, c);})([-122, 25, -1, -7, 7, -19])+'coders@gmail.com'

what does it produce ?
it's surely hiding an email address but,
how to decode it ?

thanks in advance,
regards.
Matteo
