What is the simplest, briefest way to convert an object or an ArrayLikeObject to an array using jQuery? -

-

given object 

  var obj = {0: "a", 1: "b", 2: "c"};

and expected result

  var arr = ["a", "b", "c"];

or arraylikeobject

  var divs = document.queryselectorall("div");

with expected result

  var arr = [<div>a</div>, <div>b</div>, <div>c</div>];

the expected results returned using $.map() described @

question:

what simplest, briefest approach using jquery convert object or arraylikeobject array ?

use $.merge()

jquery.merge( first, second )

first
type: arraylikeobject
first array-like object merge, elements of second added.

second
type: arraylikeobject
second array-like object merge first, unaltered.

var obj = {0: "a", 1: "b", 2: "c"};  var arr = $.merge([], obj);  console.log(arr);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">  </script>

var divs = document.queryselectorall("div");  var arr = $.merge([], divs);  console.log(arr);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">  </script>  <div>a</div>  <div>b</div>  <div>c</div>

alternatively, use $.extend()

var obj = {0: "a", 1: "b", 2: "c"};  var arr = $.extend([], obj);  console.log(arr);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">  </script>

var divs = document.queryselectorall("div");  var arr = $.extend([], divs);  console.log(arr);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">  </script>  <div>a</div>  <div>b</div>  <div>c</div>

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
