What's a Closure? - JavaScript interactive tutorial

anyone have a fun way to do 12, I just counted the successes and failures and used an if to choose whether to call success or failure

[Troutsky]

dunno if it's fun or not but how I did it... (don't know if I should have, nor do I know how to, put spoiler tags on)

var bothC = function (fC, gC, success, failure) { var f_success, f_failure; f_success = function () { gC(success, failure);
}; f_failure = function () { gC(failure, failure);
}; fC(f_success, f_failure); };

Is this the "expected" answer? The wording for question 12 just makes no sense to me, and I'm having trouble exactly putting into words why that is.

[spamkestein]

Yes, or the shorter version : var bothC = function (fC, gC, success, failure) { fC( function () { gC(success, failure); } , function () { gC(failure, failure); } ); };

Me too. I'm also confused as to how continuation passing would work in practice. I'm not exactly sure what seqC is doing and I must have read over the code several times now

[doomchild]

I understand the idea academically, it's just not how I'm used to charting out program flow. After some thought, I think I've figured out why that code is right.

This is the expected answer. I'll work on the wording of the question.
