JavaScript is an event-based imperative programming language (as opposed to HTML's declarative language model) that is used to transform a static HTML page into a dynamic interface. JavaScript code can use the Document Object Model (DOM), provided by the HTML standard, to manipulate a web page in response to events, like user input.
Dispose pattern. In object-oriented programming, the dispose pattern is a design pattern for resource management. In this pattern, a resource is held by an object, and released by calling a conventional method – usually called close, dispose, free, release depending on the language – which releases any resources the object is holding onto.
The terminology of finalizer and finalization versus destructor and destruction varies between authors and is sometimes unclear.. In common use, a destructor is a method called deterministically on object destruction, and the archetype is C++ destructors; while a finalizer is called non-deterministically by the garbage collector, and the archetype is Java finalize methods.
The name "C sharp" was inspired by the musical notation whereby a sharp symbolindicates that the written note should be made a semitonehigher in pitch.[38] This is similar to the language name of C++, where "++" indicates that a variable should be incremented by 1 after being evaluated.
C# implements closure blocks by means of the using statement. The using statement accepts an expression which results in an object implementing IDisposable, and the compiler generates code that guarantees the object's disposal when the scope of the using -statement is exited. The using statement is syntactic sugar.
Cascading Style Sheets(CSS) is a style sheet languageused for specifying the presentationand styling of a document written in a markup languagesuch as HTMLor XML(including XML dialects such as SVG, MathMLor XHTML).[1] CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.
A drop-down list or drop-down menu or drop menu, with generic entries. A drop-down list (abbreviated drop-down, or DDL; [1] also known as a drop-down menu, drop menu, pull-down list, picklist) is a graphical control element, similar to a list box, that allows the user to choose one value from a list either by clicking or hovering over the menu.
C# has a static class syntax (not to be confused with static inner classes in Java), which restricts a class to only contain static methods. C# 3.0 introduces extension methods to allow users to statically add a method to a type (e.g., allowing foo.bar() where bar() can be an imported extension method working on the type of foo).
