so tl,dir; avoiding static methods helps us to work around one of Java's defects. but it comes at a price of course

sorry for all the socratic questions -- looking back, I really sound like an ass

and so whether one chooses to use statics or to inject everything -- the solution will be unnecessary complicated, due to Java

because of the way java forces us to use statics and methods, things get complicated -- that would otherwise be much simpler

something which maybe I didn't do a good job of explaining is that I feel that the Java language is part of the problem

@bstempi I have to apologize, but I no longer think I get what you're asking -- and I haven't mentioned testability a single time. ... ??? Given the paragraph I quoted, I thought your question was something along the lines of what are some of the issues involved with using static methods in a factory; I have tried to answer that. Again, sorry if that's not what you're looking for.

@bstempi I'm sorry, but I can't help feeling that you're moving the goalposts (again, I apologize if you're not). If those extra details are important to the question, I would recommend adding them to the OP.

@bstempi it seems we simply don't agree on the points I've made -- I guess I just place more importance on coupling and higher-order code than do you. Which is not to say in any way that you're wrong. Just that we disagree.

@bstempi why do you think they didn't play a part in your answers? Looks to me like they did. Why do you think they would say something like "it's good to inject everything"?

@bstempi but it seems you've missed my points about coupling and passing methods around.

@bstempi I was going for a bit of Socratic method there. I guess I suck at it.

@JimmyHoffa no problem, good luck :)

haven't tried it yet

it's possible that let will also help: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

@JimmyHoffa exactly, you can't assign inside a single function because the assignment won't get executed until later ... when the outer variable has already changed to a different value

@JimmyHoffa yeah -- so there's really just one kk variable, and all of the closures point to it by reference

@JimmyHoffa right, you can only create variables in a function scope or in the global scope

@JimmyHoffa but where is j ?

yes? is that similar enough? making sure that we're on the same page

but without the jquery dependencies

var fs2 = [], k = 0;
while (k <= 4) {
    var kk = k;
    fs2.push(function() {
        return kk;
    });
    k++;
}

this is similar to your example:
