The example in my comment above shows that because the foo() function has asynchronous code in it, bar() does not fire it's content after foo()'s content is done executing, even using $.when().then() to call them one after the other. This answer is only valid if (and only if) all...
Check if a variable is of function type
...e are several ways so I will summarize them all
Best way is:
function foo(v) {if (v instanceof Function) {/* do something */} };
Most performant (no string comparison) and elegant solution - the instanceof operator has been supported in browsers for a very long time, so don't worry - it will ...
Java, List only subdirectories from a directory, not files
...ifying any depth limitation, it would give :
Path directory = Paths.get("/foo/bar");
try {
List<Path> directories =
Files.walk(directory)
.filter(Files::isDirectory)
.collect(Collectors.toList());
} catch (IOException e) {

C++ inheritance - inaccessible base?
...
You have to do this:
class Bar : public Foo
{
// ...
}
The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

Can I change the height of an image in CSS :before/:after pseudo-elements?
...t the content as such. Different browsers show very different behaviour
#foo {content: url("bar.jpg"); width: 42px; height:42px;}
#foo::before {content: url("bar.jpg"); width: 42px; height:42px;}
Chrome resizes the first one, but uses the intrinsic dimensions of the image

Why can I use a function before it's defined in JavaScript?
...in normal top-down order.
