this question has answer here: using .slice method on array 1 answer var array= ["a", "b", "c", "d"] var finalarray= array.slice(2,2); console.log(finalarray); this returns: finalarray=[] i return: finalarray=["c","d"] the first argument index @ begin extraction, , second 1 index before end extraction. so, last 2 elements (indexes 2 , 3), need this: var array= ["a", "b", "c", "d"] var finalarray = array.slice(2, 4); // or slice(2), since 4 length of array console.log(finalarray); more info on array.prototype.slice() available in mdn documentation .

i have test scripts add emails mailchimp mail list (among other actions). use real gmail address variable tag (e.g john.doe+12122121212@gmail.com), tool might detect fake email addresses. yet after few runs mailchimp figures , generates 'that user added many lists' error. any advice how fix test? i considered creating large pool of gmail addresses alternating randomly seems solution (not sure 100% legit ...). there few less known disposable email api pass real mailchimp, yet not 100% sure there risk in api provider discrete, , revealing company info (i.e. email designs) third parties/competitors. creating 12122121212@gmail.com might affect delivery rating. theoretically can ask developers generate special error code case, rather avoid if possible.

the testing package available in go playground. how can use go playground demonstrate testing concepts, without access go test ? my assumption it's possible using testing.runtests function. attempts generate "testing: warning: no tests run". example: https://play.golang.org/p/pvrcmdexhx for context, use case sharing quick examples of tests, examples , benchmarks colleagues. rely on go playground sharing code snippets often. you need use testing.main : func main() { testsuite := []testing.internaltest{ { name: "testcasea", f: testcasea, }, } testing.main(matchstring, testsuite, nil, nil) } https://play.golang.org/p/dqsigknwwd if want use "non deprecated", unstable way: https://play.golang.org/p/4zh7didcap

i have data set multiple columns. using r want keep column have first character t create subset shown in output data below. input data t1234 t5678 t9101112 b d e 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 output data t1234 t5678 t9101112 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 any suggestion how can achieved? thanks. in base r using regex df <- data.frame(t1234=rep(1,7),t5678=2,t9101112=3,a=4,b=5,d=6,e=7) df[,grepl("^t",names(df))] the regex pattern ^t matches t @ beginning of each row name. refine pattern ^t\\d+ if wanted match "t" followed 1 or more numbers, example. also note ^ asserts you're @ beginning of string. without you'd match "at912340"

i have 50 buttons in application. buttons created handler way: @fxml protected void handlefoobuttonactionevent(actionevent actionevent) { ... } this way user can press buttons using mouse left button or space key. however, normal practice (as know) allow user press button using enter key. possible make buttons having actionevent handler (see above) handle enter key in javafx, example if have reference stage stage , scene scene or parent root ? you can configure scene it: scene.getaccelerators().put( keycombination.valueof("enter"), () -> { node focusowner = scene.getfocusowner(); if (focusowner instanceof button) { ((button) focusowner).fire(); } }); you can event handler: scene.addeventhandler(keyevent.key_pressed, e -> { if (e.getcode() == keycode.enter) { node focusowner = scene.getfocusowner(); if (focusowner instanceof button) { ((button) focusowner).fire();
