Constructor overloading is not available in As3. In order to provide a different way to retrieve an instance of a class, a public static method can be provided to serve as an alternative "constructor". An example for that is flash.geom.Point, which represents a 2D point object. The coor...
When an extension method returns a value that has the same type as its this argument, it can be used to "chain" one or more method calls with a compatible signature. This can be useful for sealed and/or primitive types, and allows the creation of so-called "fluent" APIs if the me...

There are situations when you need to calculate something really large in your Flash application, while not interrupting the user's experience. For this, you need to devise your lengthy process as a multi-step process with saved state between iterations. For example, you need to perform a background...

A common way to download Go dependencies is by using the go get <package> command, which will save the package into the global/shared $GOPATH/src directory. This means that a single version of each package will be linked into each project that includes it as a dependency. This also means that...
struct A { ~A() noexcept(false) try { // destructor body } catch (...) { // exceptions of destructor body are caught here // if no exception is thrown here // then the caught exception is re-thrown. } }; Note that, although this...
With Maven you can create Vaadin project with vaadin-archetype-application archetype. You can also add that archetype in IDE to create maven project with IDE. mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7....
Elm has a special syntax for lambda expressions or anonymous functions: \arguments -> returnedValue For example, as seen in List.filter: > List.filter (\num -> num > 1) [1,2,3] [2,3] : List number More to the depth, a backward slash, \, is used to mark the beginning of lambda ex...
It is very convenient to use extension methods with interfaces as implementation can be stored outside of class and all it takes to add some functionality to class is to decorate class with interface. public interface IInterface { string Do() } public static class ExtensionMethods{ pu...

dotimes is a macro for integer iteration over a single variable from 0 below some parameter value. One of the simples examples would be: CL-USER> (dotimes (i 5) (print i)) 0 1 2 3 4 NIL Note that NIL is the returned value, since we did not provide one ourselves; the v...
dolist is a looping macro created to easily loop through the lists. One of the simplest uses would be: CL-USER> (dolist (item '(a b c d)) (print item)) A B C D NIL ; returned value is NIL Note that since we did not provide return value, NIL is returned (and A,B,C,D are ...
Method chaining is a programming strategy that simplifies your code and beautifies it. Method chaining is done by ensuring that each method on an object returns the entire object, instead of returning a single element of that object. For example: function Door() { this.height = ''; this.w...
