javascript - insert a new document from querying combined collection -


i new nosql world , meteor, have 2 collections, taskcollectioin , workerscollection , goal match each task available timeslot in workerscollection. tasks collection has fields {client,task-name,time-flag,assigned=false} , workers collection has field {name, timeslot:[slot, available]}. have created result collection called matchcollection result need insert document resulting in matching of each task available worker.

my question: since dealing querying 2 different collection , comparing field matching, how implement function in meteor solves following psuedo code algorithm?

'for each task taskcollection    | if (assigned == false)    |  |  task flag(for example: 10-12 pm)         | endif       |  each worker collection    |  |  **get worker slots    |  |    if (worker timeslot availible given task time-flag)    |  |    |   1-assign task worker    |  |    |   2-set task assigned true    |  |    |   3-set timeslot.available false    |  |    |   4-create document in matchcollection    |  |    end if     |  endfor         endfor'

you achieve using aggregation... here have study part.

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...
