This whole "too many parens" thing has nothing to do with the language
and everything to do with the programmer.
I googled "javascript example callback code", took the second hit (the
first hit seemed to go to a page with VB code; go figure) and the
first snipped of javascript code. Guess what it ends with. Did you
guess this:
console.log(data);
});
});
});
? Right on!
(Amusingly, the rest of the blog post seems to be about avoiding the
nesting by giving things names :).
