the typescript doc says following code: interface clockconstructor { new (hour: number, minute: number): clockinterface; } interface clockinterface { tick(); } function createclock(ctor: clockconstructor, hour: number, minute: number): clockinterface { return new ctor(hour, minute); } class digitalclock implements clockinterface { constructor(h: number, m: number) { } tick() { console.log("beep beep"); } } class analogclock implements clockinterface { constructor(h: number, m: number) { } tick() { console.log("tick tock"); } } let digital = createclock(digitalclock, 12, 17); let analog = createclock(analogclock, 7, 32); ... because createclock’s first parameter of type clockconstructor, in createclock(analogclock, 7, 32), checks analogclock has correct constructor signature. however, compiling same code without constructor, not throw error can see here why that? missing anything?

i found weirdest behavior in linq: when calling unary functions pass function name, instead of var foo = mylist.select(item => myfunc(item)); i write var foo = mylist.select(myfunc); which should same. in cases, isn't! namely if function has second parameter int , optional: private string myfunc(string input, int foo = 0) { ... } in case, statement var foo = mylist.select(myfunc); equals var foo = mylist.select((item, index) => myfunc(item, index)); if second parameter either not opional or not int , compiler complains, in case, sneakily surprises you. has else encountered this? other linq expressions work way? (so far, .selectmany() does). , elegant way work around behavior (and keep others falling same trap?) this not issue of specific linq extension method, how optional parameters handled func s , action s, in short - not, considered regular parameter , default value omitted when selecting corresponding func / action signature. ta

i watching programming languages courses given prof. shriram krishnamurthi on youtube. in episode, https://youtu.be/suh7jhrtktk?t=1600 he said conflating environment , objects fundamental sin of javascript. environment exposed language users, , users can manipulate environment. i don't quite understand means actually. refer how "this" works in javascript? are there code examples can demonstrate sin? after little bit of digging, i’ve found paper professor shriram’s group. https://cs.brown.edu/research/plt/dl/jssem/v1/ in section 2.5, pointed out not clear whether javascript lexically scoped because scope chain in javascript formed ordinary objects, , with statement lets programmers add arbitrary objects scope chain. i think understand means in video. i highly recommend paper. indeed catches of essence of javascript according title, not part, bad part.

running cucumber in circleci selenium tests fail due circleci's performance. common failure net::readtimeout error, never seems happen locally. want rescue steps error , try them again, not want rerun failed tests. i put build rescue specific step(s) seem trigger error, ideally able provide cucumber list of errors rescues once or twice, rerun step, before letting error pass through. something like: # support/env.rb cucumber.retry_errors = { # error => number of retries "net::readtimeouterror" => 2 } does exist? i surprised if found looking in cucumber. re-running failing step make sure actual failure , not random network glitch is, perspective, solving wrong issue. my approach see if verification looking possible without network. might consider using other tooling cucumber if must re-run few times make sure error error. would, however, lead me down rabbit hole. how many times should run, threshold? should 3 out of 5 executions pass dec
