looking @ docs systemjs can not find example of loading multiple dependencies @ same time. expect api like... system.import(['jquery.js','underscore.js']).then(function($, _) { // ready go both jquery , underscore... }); i expect use promises load dependencies in parallel, , execute callback once complete. possible? if not, there reason why functionality not implemented? this possible promise.all: promise.all([ system.import('jquery'), system.import('underscore') ]).then(function(modules) { var jquery = modules[0]; var underscore = modules[1]; }); but ugly can see. there talk of considering allowing array example @ spec level, need in module spec since spec loader. the better alternative have 1 entry point application, app.js , have load dependencies.

i noticed when run pyqt application , close it, application closes , process still alive. apparently process running not close after closing application. traceback (most recent call last): file "f:\projects\xyz\xyz\xyz.py", line 414, in <module> sys.exit(app.exec_()) systemexit: 0 when searched online , says if return value 0 , normal termination. see process keep on pilling run application. so how overcome problem? this looks problem specific idle. there several issues on python bug tracker closely related (e.g. 8093 , 12540 ), closed , resolved "fixed". since appears using old version of python (2.5), should able solve problem upgrading.

what simple method return array key when using array[] add new values. for example: $array[] = 'hello world'; return $key_of_hello_world; the method i'm thinking of involves: $key = count($array)-1; is there different solution? conclusion a combination of end() , key() best in general allows associative if array uses numerical keys, count()-1 seems simplest , fast. added other linked question. $array[] = 'hello world'; end($array); // set internal pointer end of array $key = key($array); // key of element internal pointer pointing @ return $key;
