node.js - use async auto as wrapper -


my synchronous code near thousand of lines. want divide them groups , put in async.auto (one group 1 function in async.auto). each function has name. because want make easy other people maintain in future. code divide group easy understand. want know async.auto cause performance loss comparing when don't use 

do stuff; stuff; stuff; ... stuff;

i want change below:

async.auto({    do_a: function(cb){       stuff;       stuff;    },    do_b: ['do_a', function(cb, result){       stuff result;       stuff result;    }] }, function(err, result){  })

you should able divide , put separate functions async.auto large blocks of synchronous code there lot of coupling between different sections of code without realising. advice split up, testing each time create new group , commit change scm (e.g. git) before beginning next change. way when discover problems can go , find out introduced it.

i don't know enough performance impact would think minimal. best bet (as performance question) test in profiler. won't performance benefits either unless let run of functions out of order. if every block depends on previous 1 run in sequence.

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
