Re: [Proto-Scripty] Re: local variables for for() array iteration
Hmm, it' is the prototype way of doing it. I suppose it has to do with
writing beautiful code, but that might be a matter of taste. Some like
it and some don't :-)

Whether I'm using Prototype or not, I don't need to create a function
and incur the overhead of a function call on every iteration (not to
mention the complications around `this`) just to loop through an
array. People are free to do that if they like, but it's not remotely
necessary and it's certainly not always appropriate. There's nothing
wrong with a nice, simple `for` loop.
Just my two cents.

Re: [Proto-Scripty] Re: local variables for for() array iteration
Thank you for the advise.
one more / last question to clarify.
In one of the articles about javascript scopes I read that using var
inside a class constructor actually
creates a private member of the class. is it true ?
if this is true, then should I avoid using
for (var i=0;iarr.length;i++)
like statements inside a class constructor ? because then i would become a
class member,
and then using var i inside class function is not safe.
am I right ?
