The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. The examples below make use of the log function of the console object present in most browsers for standard text output. The JavaScript standard library lacks an official standard text output function (with the exception of document.write).
It cannot be used to remove text in expressions for template names, parameter names, parameter values, page names in links, etc. To view hidden text, download the Web Developer Toolbar for Firefox here, then choose Misc. → show hidden elements in that toolbar.

To distinguish a fully qualified name from a regular name, C++, Tcl, Perl and Ruby use two colons (::), and Java uses dots (.), as does Visual Basic .NET. [3] and C#. [4]In Java, ActionScript, [5] and other object-oriented languages the use of the dot is known as "dot syntax". [6]

In the previous example, the class Component is inherited by both the ConcreteComponent and the subclasses that descend from Decorator. The decorator pattern is an alternative to subclassing . Subclassing adds behavior at compile time , and the change affects all instances of the original class; decorating can provide new behavior at run-time ...

For example, if a page contains a "span" element with class FA and id lc, MediaWiki:Monobook.js specifies the style and title of elements "li" of class interwiki-lc, thus controlling the style and title of the interlanguage link of language code lc in the margin, provided that the skin specifies this class interwiki-lc (E.g., Cologne Blue ...
